Hi,
I had a Central Machinery saw for two or three years. It worked surprisingly well, especially for the money involved. However, using only pin-end blades is quite limiting. You can purchase 3rd party "kits" that will allow you to use pinless blades, but they are relatively expensive, and you still end up with a Central Machinery scrollsaw. I gave mine away, and moved up to a Porter-Cable scrollsaw (Lowes), which was still under $300. It's been much more satisfactory, but in all honesty I have to admit that I'm saving my shekels for a DeWalt 788 or a Delta 40-690.
