Suggest me a good camera to buy in around $500?

I'm planning to buy nikon p 510. Can any one suggest me a better camera other than this in SLR category with the nearest budget of it? My budget is around $500 or 25000 INR

With your budget, the P510 may be at your budgets limit.

For $700, you can buy an entry level dSLR like the Nikon D3200 or Canon T3i/600D

Visit a proper camera shop and see if it is worth it to you to budget for $200 more for a camera with interchangeable lenses and a sensor that is over 15 times larger than the P510

For just another 50 or so - a Canon Rebel t3.
