There has only been one time when I purchased a tool that I disliked before I even owned it, and that would be the day I purchased my 40' ladder. I hate that thing, and I can't imagine using a 60'!!!
@ the OP, there is a huge difference between a rotary hammer and a a standard 5/8" hammer drill. I'm pretty sure you can rent one if you want, or you can typically snap up a used one in decent condition off of craigslist.com or a pawn shop.
