Having a second thought!

i've done both, new on payments back in '96, had balls of fun with minimum maintennce for 8+ years.
never once regretted that $90/month payment.

but a stock blaster would never cut it again once i've moodded them.
so, used and modify it to your specs is the way to go.
parts/mods are everywhere, for relatively cheap.
build a beast for less than the cost of an under powered/suspended/braked new one.

but, thats here in the states.
