My wife and I have been coming here for about ten years for woodworking supplies, machinery, and wood. We love this place. First, it is HUGE. There's one large building for machines and supplies, and another for lumber. The machine selection is excellent. Prices are pretty normal, mostly MSRP on most machines. They also have used machines that are often an excellent value. We've bought a few and never had any issues with them. Also picked up a lot of used DC pipe for less than half the cost of new.
Everyone seems friendly and helpful. As with any other hobby, some of the employees know more about one thing or the other, but you can always find someone with expertise in what you want to know. They've always been friendly and helpful.
