I have no experience with that particular model, but I started out on a Craftsman about 20 years ago. It was a serviceable machine, but I quickly outgrew it and wanted something better. I wore it out after several years and replaced it with a Dewalt. I now have an Excalibur. None of that is really relevant to your question though. The thing about mid-priced scroll saws is that many of them have very similar characteristics. There may not be much difference between models across several brands.
With regard to the specs of the saw, generally speaking variable speed is good to have, but if you do much fretwork, you may grow to hate having to use a tool to make blade changes. Vibration is probably tolerable. If it's too bad, be sure to get it replaced while under warranty. The 16" throat depth can be somewhat limiting, depending on what you are cutting, but it should suffice for most beginner projects.
It's a bit of a catch 22 with these saws as beginners don't want to spend a ton of money on a tool until they know they want to pursue the hobby long term. But low to mid priced saws aren't designed & built to the quality of the more expensive saws and the lower quality may lead to a less enjoyable experience, frustration, etc and eventually abandoning the hobby. We don't want that, so if you do find yourself frustrated, post your problems here for advice on how to distinguish between problems with the equipment vs technique. Good luck!
