I found a new 2007 Dk General Lee for 150..should I get it? I'm used to ride bmx a few years ago and switched to track bikes and now I think I wanna buy a new bmx..is it worth it? if not, what brands should i start out with?

I don't know, but I do love the General Lee BMX bikes. Only because some guy races one every year in our local Cyclocross Single Speed races.

Here's a link to the start of one of last years races.

Notice the General Lee pulling the slack in last place - tough to compete with 700cc wheeled bikes. Based on this I would say hell yes, get the General.

haha, that video is pretty funny.
if i were you id just buy it. i mean 150 is pretty cheap for a new bike. and if youre just gonna be doing some basic tricks not dropping 30 foot pipes or something, in my opinion id say a general lee should be cool
