$435 wow! I'll have to go look that up. I know the reamers are a bit expensive but they must have something else there. My reamer was $40 some odd from eBay, correct taper 7.something*. The offroad guys use a drill, LOTS of cutting oil, and go slow and test for a lot. IIRC Ruff Stuff also sells hardened steel inserts that you drill out the knuckle to 3/4" and weld them in. Gonna check that kit out just out of curiosity.
EDIT: Never mind, I see what you meant now. Cheb 1 ton TRE's are so a good idea for off road/on road guys to stay DOT lethal and have beefier tire rod ends that can take more abuse. I'll only be reaming my pitman arm and going high steer with both D60 swaps...whenever I cab get around to starting on that.
