I just replaced my Dremel 6300 Multi-Max oscillating saw, which failed horribly after about an hour of runtime over several small projects. Home Depot was good enough to take it back (within the warranty period) and not make me deal with Dremel as directed on the warranty form. I took the credit and traded up to the Bosch MX25E. It's much heavier than the Dremel, which I take as a good sign. The tool was made in Malaysia, the blades were made in Europe, and the storage bag was made in China.
It came with several blades (what you get will depend on exactly which specific kit you buy) and an adapter plate that's supposed to let you use accessories from other manufacturers. The adapter plate just presents a bunch of hard, somewhat sharp points to a non-bosch blade, so you should be able to use it with anything that fits over the mounting screw regardless of the pattern of studs it was designed for. Unfortunately, you do have to completely remove the screw to change blades. Even the Dremel had a slightly faster option.
It also came with a nice box to organize accessory blades in, and I prefer the heavy cloth storage bag over an inflexible plastic clamshell case.
I used it last weekend to cut the lath in the ceiling of our upstairs bathroom for a new ventilation fan. So far, so good. If you work with lath and plaster construction, these oscillating saws are great. Score and chip off the plaster with a knife, and cut the exposed lath with the saw. The high-speed oscillating action doesn't vibrate everything and damage the adjoining plaster like a sawzall or hand saw. It's house surgery with one of these things.
