Any idea how much is the weight for the Focus?
Reading from the review you mentioned it is 23 pound or 10.4 Kg (60cm frame) .
Other review on bicycling.com mentioned 21.4 pound or 9.7Kg for XL size.
Comparing the Focus to Giant TCR SL2 2012 (7.9KG) @ RM4.8k (quoted by one of Giant dealer, before nego), is the saving of ~2Kg worth the extra RM1k?
Both having similar white colors, 105...

bike weight claims are very hard especially when comparing between models from different manufacturers... that is unless they come to state a claimed weight for a particular size.. which is why most manufacturers stay away from it nowadays.+
so when you put a focus in question with a giant... the first question comes first, did the majority of the weight savings came from the frame or components?
frame
the focus is a 60cm in the review and as you mentioned from bicycling's review of an XL which is 58 is almost 700grams lighter (which i pretty much doubt) if they are both weighing in the same manner and their scales are calibrated correctly... most of us asians unless you are yao ming sort of height would be getting something in the range of a 48 to 52cm..54cm at max so it might be as low as sub 10kgs easy and not accounting for the 32 spoke wheels vs what i think is a xero xr-200 (sub 1700gram vs a tad over 2000grams easily)
if the giant frame really did get so much weight savings compared to a focus, then the question is did they manage to skimp on materials to make the frame lighter and end up compromising the stiffness of the frame or did they use a different grade of aluminum than focus did.
components
giant did fit the SL2 with some fairly nice cockpit, composites seatpost and high grade alloy bars and stem which accounts for some weight savings
if you really are looking at an TCR SL and not a TCR, you do have to bear in mind the one important thing. TCR SL runs on the new overdrive 2 which they launch for 2012 models. This means both the stem and headset is now specifically for their fork steerer tube which is slightly larger than most current standards. You might have trouble finding a different sized stem if you have fitting issues or even a replacement headset when the fitted one wears out. If your shop has the stem and headsets in stock, then no big issues. Just a limited brand options to choose from.

at the end of the day, if most of the weight came from components and you know you will be itchy handed some 6months down the road after purchasing it, then here is where i think the focus is no different from a giant since you will be swapping all the stuff that is saving you the weight in the first place. If the frame is the main weight saver, then giant is a good place to start with if $$$ not an issue.
Decisions, decisions. personally, i would go and weigh the bike bike at the shop first with both weight on a similar manner, no pedal, bottle cages and any other extra clamp on stuff.

Around 5k+ you can already to get entry carbon frames with some lower group components. For me weight doesn't really matter too much my body weight alone could have surplus the differences of the bike
you can't really get a carbon bike at RM5k unless you are looking for those taiwanese brands like stepdragon, tw26 and whatever i have yet to see before... the carbon frame is cheap but so does the quality of the layup work of the material in the building process..reputable brand's entry level carbon with shimano workhorse groupset like 105 goes for RM10k starting.
as i mentioned above, an alloy frame is very finicky as metal fatigue is an issue... if they skimp on materials on sections where they think bears little stress to make the frame light.. the frame will begin flexing more due to fatigue some 2 or 3 years later depending on your ride volume and especially when your body weight is in the upper regions of your scale.
this is the downfalls of alloy frames compared to carbon which has no fatigue life... but this allows beginners some leeway especially when you have a tendency to crash it... alloy is more crash worthy compared to carbon in this sense.. and less expensive to begin with.
i've gone through 3 bikes in the last 4 to 5 years not because i am finding excuses for a new one (partly i have to admit is an excuse) but also that i felt the frame has deteriorated over time...don't ride carbon cause i can't afford one and don't have a good sense of balance..
