No idea who makes the F3. I will say, the reason I did not look at it seriously is the very short distance from blade to front edge. Otherwise, very good reviews. Of course, there are several ways to make clamp on front extensions or for that matter, move the fence rail and add a spacer for a couple inches.
If you can afford the PCS, by all means. A very good saw. I hope I never regret ( by an oops) buying the Harvey. I do like it very much. I too went for 36 inch and a track saw. I can't handle a 3/4 inch sheet of BB by myself anyway. The F3 was said to "run as smooth as a Powermatic" Did not saw which one though. The only performance gripe I have with the Harvey is I wish it had a multi0rib belt rather than 3 v-belts. They do run smoother. I have not swapped the Chinese OEM belts for good Gates AX series yet.
All the prices have gone up, so what is a good deal, I no longer know. Harvey is not as cheap as they were relative. Maybe the others had more margin to start with so did not have to jump as much. Shipping is a much bigger deal than it was.
I had an idea on how to modify ( or supercooltools) fence to gain about another 6 inches or more. Convert the "T" to an "L" Same overall stability, just further over. Maybe one of these days. One could also make additional fences with a longer "L" just for wide sheets. But really, if I can reach the center of a 60 inch Birch ply, I guess I am good.
