I've been using one for a few months now...it's held up pretty good so far...here's what I got for spares:
Factory team hingepins (stockers bend easy)
Ver. 2 front arms (not graphite unless you never hit stuff)
Extra suspension mount set (they get ripped out in a hard hit).
You might want to get some C-hubs and uprights...but I haven't broken those yet.
So far all I've killed are two front arms...no bent pins or mounts ripped out since I got the good ones.
Get an RPM front bumper and you should be set.
Oh yeah...I'm a novice with a heavy trigger finger.
