With a couple oem parts, 066 clones are very reliable, that's a non issue but the 670's probably a better size for the wood I cut.I would still grab my Pro Mac 700 and my Jonsereds 670. Both are stone reliable with a 24” on the Jonny and a 28” on the Mac. Second choice would be my 800 Pro Mac and my Partner P70. Again reliable.
I kinda wanted a 272 or 670 but they cost a fortune, it was cheaper to get the bigger clone.
