Brand spanking new EX-21, which is 3 inches bigger than the Hegner, is on sale for $679, but does not include the stand..which you can just make your own better one that what they sell anyhow. The excaliber saws don't have to have a stand, they can be used and transported like a sewing machine..part of what makes them so great is their portability. This way you get a saw brand new with warranty, all the parts, manual, guaranteed no bushing wear. That's at Seyco.com I think excaliber is now owned by General Tools and built in Canada..don't quote me on that.

Those are probably your best three choices for a saw. You can buy a saw for $20, but a cheap saw will turn you off scrolling. If you don't know if you like scrolling, but you want to give scrolling a fair chance, I'd buy the Dewalt. Then if you really love it, you can upgrade and get a good chunk of your money back on the resale of the Dewalt. That would be my advice.
