i hear good things from the Azonic steelhead frame. Cost is $150 from beyond bike which is local to us. Or you can do what I did, I got a trek bruiser 1 for $350 and it was enough to get me rolling and thrashin the local stuff and leave the XC for the easier less harsh rides. I'll upgrade as a go. The main weak point on the bike has to be the rims, they come un tru often, but I'm also 200lbs. The cheap fork holds up well, i've done a few 4-5ft drops to flat without bottoming out. You can get a Giant STP3 for $400 which is good for DJ's and Urban riding and upgrade from there. I hear they have weak cranks though. If you can shell out $600, u can get the trek bruiser 2, STP 2, P1 (single speed), or kona shred. All come with mech disc brakes and Marz MZ comps forks or simular.
