I got the 735 last year around Christmas, I don't think the current ridgid models were out then or either I overlooked them. At the time, Lowe's had a 10 or 20% off sale on the power tools, so I went ahead and made the jump. I was sold on the two speed feed and three blade cutter head.
I've only used it a few times so far, just playing really to see how my lumber was turning out, maybe having run 20 or so 10 to 12 foot, 8 to 10 inch oak and popular boards through it, oh and a couple treated 2X6's too.
Results are nice finish with no noticible snipe (not noticible at my experience level anyway)....I definitely plan to get the extension tables and to set up a longer support rest of some type before I get to serious thicknessing. Chip extraction has been great and the built in blower actually chews up the chips finer than usual, chips from this unit look like chain saw chips, not the typical curlys from most planners. A big benefit of that is less tendency to clog the dust collector stuff, but more messy if you just blow them out in the open.
It could use more power, but then what couldn't?
I initially had infeed problems, but it turned out to be build up on the rolls from the treated wood I had run through it. keep the rolls clean and it works great.
