Question for head porters

I want to start doing this and am wondering what kind of grinder you use? I have air but would rather have something electric if I can find something thats gonna last for a long time, I dont mind spending a cpl extra bucks for something thats gonna last for a really long time and be of good quality. I was BSing with the machinist I use and he says he gets his bits from snapon and they have the lifetime guarantee like the tools so when they get dull his dealer just exchanges them for him which is cool. Not trying to set the world on fire, I just like to do as much work as possible on my rigs and rigs I work on. Im slowly accumilating the assorted tools I need to build and set up heads(porting heads is also something I'm really intrigued by hence the question). Anyways, thanks for any info you can give me about the grinder as that's the next thing I want to get. I didnt know where to post this,hope this is ok.
Thanks,
Marvin Jr
