I just got off the phone with them and they were very inormative. I have not yet bought a stringer, but am close. I am confused with the numerous models they have. It seems like some are great bargains and others are not. The model I'm looking at, flex 740, has 6 point mounting and swivel clamps, all for $239. No one else can come close. I understand their service isn't the best, but with their machines costing only 50% of traditional brands, I'm willing to deal with a little slowness. How much maintenance is needed on a stringer? It seems like a sturdy piece of equipment that if all the parts arrive should work for years on end. thanks!
