$200 is a pretty healthy budget. It should allow you to get your hands on pretty much anything in the marketplace including a fein. Things I would look for:
1. A cord. Cordless has it's conveniences, but for me, this isn't a tool I would use day in and day out, and when I do need it, I don't care to change batteries every 5 mins. Unlike a drill, this is a tool I will turn on and use continuosly for a few minutes to 20+ minutes if I'm sanding.
2. More than 2 degrees of oscillation. Almost all the offerings are 2 degrees. The Fein supercut goes to 4 (that's way outside your budget) and I think some of the recent offerings may go to 3. The question is do any of those still fit within the budget. Worth looking into. FWIW, it might be harder to control with the larger swing, but I think that depends a lot on the machine as well.
3. Quick release (tool less) blade change. Not only handy when you need a different blade, but also when you need to reposition the blade optimal access to your cut. I've used a HF model and the screw down clamp drove me nuts every time I need to reposition the blade and it absolutely infuriated me when it backed off.
4. Cost/quality/accessibility of consumables. This is probably a smaller point than the above, mostly because there are adapters and 3rd party sources for common things like cutting blades. Bosch blades are available in retail stores and most are pretty decent quality (swiss made), but they are kinda pricey. They make an adapter so you can use them on Fein MM's.
