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.
