Fein is undoubtedly the best. They do a damped wired version which is worth it for the lower noise and vibration. It's one of the few tools where battery seems worthwhile. I only have wired and it puts me off using it sometimes. They are indispensible.
Fein originally made them for boat building and their catalogue of bits has loads of interesting solutions including cutting out silicon which they are brilliant at.
+1 I have the Fein 110V version*, and it is a pain to hump the transformer around, (but it also powers the 9inch Makita angle grinder),
and once it is out and in use, it more than saves the time & effort.
[I got a kit/promo version with dust extract and a bunch of accessories at a D&M Toolshow].
