So i've been looking into a dremel because as of late I have been giving thought to buying 20 dollar cases and cutting something cool in it, adding fan slots etc. I went to walmart and there were so many I didn't know what to get. There were corded ones and lithion cordless gun one, and others with various tools like the circle cutting tool. What should I be looking for or do you have a link to one I should pick up? Also other than PC modding what else could I use the dremel for?
