Russell, you won't go wrong with a DeWalt 788. I have that same scroll saw, a Type 2, for more than 10 years and it's great. The Type 2, designates that it is made in Asia, (if I'm correct, in Taiwan), they used to be made in Canada. The saw can be a little noisy but there are fixes for that on the net, the light didn't work for me (too hot) so I took it off the saw. I use my scroll saw almost everyday and I can honestly say that the DeWalt is a very good saw. I also have an Excaliber 21 that I use often, this is also a good saw, but in my opinion is not worth the cost. If the Rockler price is $ 400.00, I think I would opt for that. One last point, DeWalt has a program where they will do a complete maintenance on an old saw for about $250.00, and they claim the saw will be equal to new. I have not had a need for this service yet so I don't know how well the outcome is.
Good luck with your new saw.
