If picking only D7000 body, what lens you'll pick as your first? Isn't the 18-105 is a pretty decent one to start with?
Care to elaborate more on the memory card speed VS video recording speed? How does it affects the performance?

I have asked around KL and PJ, this is the cheapest which I got offered so far. Anyone from KL got any shops to recommend?
If I were you I will buy d7000 + 50mm 1.8 or 35mm 2.0 + 18-70 Nikkor or 1750 Tamron or 1850 Siggy.
Err.. I am not really sure about DSLR.
however since I am an IT-student I will elaborate the essential of memory card in IT perspective. However if you find it difficult to understand you can directly skip this part
every computer or any computerized machine is having a small built-in memory to store whatever happening before actually store it to the actual storage (the place you save your photo in this case memory card, in pc case it will be hard disk. this is called non-volatile memory the basic idea is the computer or any computerized machine can retain the information even when not powered if you want to do further research you can go here :
http://en.wikipedia.org/wiki/Non-volatile_memory)
However it is impossible for computer to directly store it on non volatile memory as it usually has slower access rate which makes you will feel the device is dumb therefore device nowadays including PC has another memory called volatile memory reference :
http://en.wikipedia.org/wiki/Volatile_memory (in PC case it will be RAM in DLSR IDK what it's called but I am sure DSLR has one as you can still store some images even you don't have the memory card, the purpose of this volatile memory is making the process is faster therefore the sequence of execution will be USER ACTION -> COMPUTER CALCULATION -> STORE in RAM -> STORE in HDD if necessary).
if you don't have the clear image of volatile and non volatile this example will give you an idea.
if I open the document and type something on my Microsoft word let say "ABC" and I didn't save it. I shut down my PC and the following day my "ABC" document lost.
it happen because I do have it in RAM so I can still see "ABC" however since RAM is volatile it doesn't store anything once you turn off the PC.
exactly the same thing happen on DSLR. Those images you captured w/o memory card will be gone once you turn it off.
however if I save it on my hard disk I can still see it later on. <- this because do save it on non-volatile memory such as hard disk..
Volatile memory is good however the main defect is it has limited amount of storage. E.g nowadays 4Gb RAM is awesome.
this makes volatile has to work together with non-volatile which can store a lot bigger number of memory. let say 2Tb HDD.
In conclusion :
'RAM' or whatsoever called in DSLR couldn't store your 10 mins movie at once.
therefore I should retain information from your sensor + lens about your recording thing (as it still go on) while it should store some information to memory card gradually before it happen to be 1 video with 10 mins length.
Therefore the speed of HDD (in DSLR case is memory card is a necessity in video recording to help the 'RAM' in DSLR stay connected with 'HDD' in DSLR w/o any delay).
again that's just what I learn trough my college life.
correct me if I am wrong.
