If you're in the market for a hand held jig saw, I've had a corded Bosch that has been a great tool. It's very smooth compared to others that I've tried over the years, and great quality. My Bosch is over 20 years old, if they still make them like they used to, I'd highly recommend.
If you're looking for a floor scroll saw machine, not sure who's making a decent one these days. Rule of thumb is that you can't go wrong with Powermatic, they're top notch. Get something with some weight to it, nothing worse than a jig saw vibrating/rattling around. I've got a made in USA jig saw that came out of a commercial wood working shop, and it runs nice.
For miter saws, I've got a no frills Milwaukee that I've had for years. It's a good cutting saw, so I've resisted buying the latest and greatest new fangled laser guided thing that's out there. If I were to get a new one, I'd probably go with a Makita. A lot of people seem to like DeWalt miter saws, but they seem kind of cheap to me...?
