i went to go pick up a DMM from radioshack and there were different types that cover different ranges..... the diff ranges were 15, 18,22,29, and 42, and one was a bit higher....they got more expensive as the amount of ranges went up?....which one do i need can i settle for the 8 or do i have to get the 42?....or is there one in between that works best?
