I was thinking about getting something new for my a200 but i don't know what to get...I have the kit lens, and a 70 to 210 lense i believe. What would be a good choice to get some overall good shots?? Flash? Smaller lens?

Depends on what kind of pictures you take.

Do you take a lot of pictures inside or outside? (Flash)

Do you take macro shots?

Do you have a good tripod?

I have a tripod its decent, i like to shoot cars, and just random things that i like. Not really scenic shots, macro i don't fully understand is that the really close ups?

Look into a wide-angle lens... i.e. 10-15mm or even the basic 18-55mm lens that comes with many cameras these days.

Thanks for the advice i'll check them out.

Double..
