Now a day, a decent tire truer is about $150-180 range (integy one)..........and I think that is one of the best bargain for low budget user, come with all the options that HUDY $500 truer does for $350 cheaper...
Your other option...........SEARS sell a decent DRILL LATHE.....of course, the main purpose is for drilling, but back to the old time, that is the way how ppl TRUE their foams, mount a metal roll as a bit, then install the tire mount, then clam the true bit on the side and start truing.....not a easy task, but probably the cheapest..
Saw one on paper on Sunday for $89.99.
If you are really machine ready and handy, build one yourself will be the cheapest............but I just don't see it will ended up cheaper then $150, not to mention the TIME and EFFORT.
