No offense, but how many machines did you try before purchasing the Revo 4000? I have a lot of experience with Eagnas own 2, and many other manufactures, and have to say I would rate the Revo as average at best. It is an old design, and offers nothing new or special. If you have an opportunity, try the Alpha Apex, it has the newer mounting system and 3 tooth clamps, plus comes with a stand for around $995 or so. The Eagnas 6500 is pretty much the same machine for $595. If you tried the Eagnas, Alpha Apex, and the Revo 4000, you will understand what I am saying. I do a lot of rackets, and absolutely hate the 6 knob mounting system (which I currently have). Like my machine, the revo 4000 is an old obsolete design.
