Recommend Bandar Puteri Puchong , Puteri 12 is good

rm 2M is a bit hard for Bungalow, or even semi in more lively place to stay. Bandar puteri is a good place,
you can search from property site for Semi D, which i assume it will fit your budget , instead of bungalow.

Place with Semi - Puteri 8, Puteri 9 and Puteri 11, Puteri 12, all are good place to stay.
Or you can call up ioi property, they still hv 1 left  10,000 sft land size / build up 4800 sft semi D, something around RM 3 mil, they may let go.
in puteri 11.

need some touch up though it is still not sold.
Else, it will be Bandar Kinrara - you can look for sub sale in mahsing kinrara residence, leasehold or chinta/qaseh by I/P (not setia)
all this are good places.  i hv all friends staying in all the above places i mentioned, each of them are happy with it.

Don't think you can get a nice condition bungalow within 2-3M budget in central Puchong.
If you can settle down with Semi-D, SkyVille or Puteri 12 are nice.
The Semi-D there is as big as those newly launched bungalow.

Kinrara is a little less lively but nearer to KL which makes the house price comparable to central Puchong.
Southern Puchong (before Bukit Puchong toll) is more lively than Kinrara but less than central, deeper inside but house price is just right for your Bungalow budget.
