This is the only power tool I have bought from Harbor Freight:
http://www.harborfreight.com/cpi/cta...emnumber=93981
I got it on sale, and with a coupon, for about $57. Always use coupons when shopping at Harbor Freight

When I got this thing home, I had to tighten EVERY bolt on the machine. After that, it seemed pretty solid.
I used it for shaping a stack of ribs for a scratch build, but it doesn't get any use on kits.
The Zona saw, GP sanding bar, a set of little squares, and tons of clamps are the most common tools I use, along with 100 packs of single edge razor blades.
I do use my 10" power miter saw and my drill press for cutting servo trays, firewalls, etc...
Good luck
