currently in the shop i work at shop there are three 10" bigfeet and one 14" and a 16" makita with the thick aluminum aftermarket base.
the older bigfoot is heavier and probably rougher(casting and baseplate). both of the new 10"(acquired via ebay)bigfeet arrived with baseplates broken through at the slot for the rip fence. they were quickly replaced at no cost, no questions asked. i generally feel it's kinda fragile and try to treat it gently. i ground the guard down a little to improve the retraction. i think the new ones bevel to 50 degrees.
the 14" bigfoot seemed pretty good right out of the box, it's the new bosch 15 amp vs the mag 77 13 amp on the smaller ones(the 10" bigfoot is available with the 15 amp bosch).
to maximize cutting depth and bevel capacity there are very large cutouts in the baseplate, which is only a problem when you are cutting near the end of a timber and the saw wants to fall off.
but, apparently the saw has developed a speed wobble when cutting anthing other than 90 degrees and is inaccurate, perhaps due to the thin kerf blade, which is about the only one available to fit the diamond arbour. the whole thing seems like it's just really good for gang cutting stick frames and that's about it, not that that's bad. doing long rips makes it stink like burning electrical bits and pieces.
i may be wrong but i don't think either of the 10" bigfeet cuts less than an inch.
all in all the 10" bigfoot seems a pretty good and easily available option. ya still have to roll an 8x8 and cut twice with a 16" saw.
