I bought this to install my maxjax in my garage. This is the first link I found but I think it was under 200$ at one of the amazon vendors (refurb).

It laughed at drilling the 6" by 1" holes in my garage. It seemed to taunt me with "is that the best you got?". Anyways no problem you could prob get away with a smaller model.
On the rent vs buy: I was in for about 210$ for the drill and bit, vs 50$ + tax + bit for rental. I was going slow and careful and it was great to not have to be in a hurry to return the tool. I figure if I use it one more time if if I lend it out a couple times it was worth buying. My buddy has already used it for a bigish job
