ghetto whomper!

i dunno much about this bike. i bought it complete from a dude in my city that rides fixed. he said it has a dope wheelset. i dunno what brand the rims or hubs are, but i do know that i don't hear a peep from them while i'm riding. the rubber is Specialized 700x23. its been good to me so far and quite fast when it gets moving. i like it but i doubt i'll keep it. i have a old school Schwinn conversion that i can ride whenever i want(my dads. he rarely rides anymore). thinking about holding on to it until i can get my hands on enough scratch to get a track bike. any ideas for a good track bike for a reasonable price that's not a kilo or a pista?

last bike isn't mine. dunno how it got there..haha
