Electric die grinder

[sambo]

I was at the Vic Cobra club meeting last night and it was widely suggested that I use a die grinder for cutting the body work instead of a dremel. Aussie Mike said to go for an air tool but I don't have the space for one at the moment, plus it's another cost. (good suggestion long term though Mike - thanks).

I've used all my google powers to try and find electric die grinders locally and haven't had much luck. I will visit Bunnings on the weekend, but meanwhile any info or suggestions would really help. Things like: angle, straight or barrel? Which attachments? Suitable RPMs? Good/bad brands?

A few of the electric ones I found are here.

Thanks in advance.
