I haven't gotten one yet thought some stereos came with kits like the one that folds out

I'm looking for an stereo around 300-400.00 what should I get.

regarding your double din stereo install, where did you find your installation kit? i have an 01 maxima and i want to do something with the double din and i cant seem to find a Brand name or anything so if you could send some info with that then it would be great.
