Bought a Spin Doctor truing stand from PBS about two years ago and I find it more than adequate for a home truing stand. Only thing that you might add to it is a wheel dishing tool, but you can just flip the wheel like I do and it still works out really good.
They go on sale once in a while at PBS for well under a hundred. I think I got mine for like 68 bucks! Some have noted that the stand is actually made by Minoura for Spin Doctor, so you can consider that if you are concerned about quality.. I've built up three new wheelsets and trued many others on the Spin Doctor stand and so far it's been good enough that I can recommend it.
Heres a pic of the rear wheel from the last wheelset I built up on it late last year:
28H Wolber Profil 20 aero rims with DT Aerolite oval spokes and Stronglight 28H Delta sealed bearing hubset.
It's the straightest/truest wheelset I ever owned so far, thanks in part to the Spin Soctor stand that was a treat to use!
