Replying to BMX help

Ok, so here is the story. I have a specialized p.2 DJ bike that i want to sell and buy a bmx. the p. is a fun bike, no doubt, but i want to get more in to street riding, and the p. is a bit too big and heavy for me. I ride lots of dirtjumps, and a little street on my p. I want to buy a BMX, but not sure exactly which one. I want at the very least a 20.5"  top tube, preferably 20.75 or longer. I want it to be relatively affordable, so not more than $5 or $600. I also want it to be as light as possible. im not very heavy, so not too worried about breaking it, and i like lighter bikes anyway. So far, i have been looking at the Eastern Shovelhead, Subrosa novus dirt, Stolen score, and Fit TRL2. Does anyone have some other reccomendations? thanks alot
