Thanks all! A quick search shows some refurbished rotary drills in my price range.

I have been using the DeWalt DC725 1/2" Cordless Hammerdrill/Drill Driver to drill holes into poured concrete with 1/8" and 3/16" DeWalt masonry bits. I hadn't ever drilled into concrete before. It is taking me a good 10 minutes to drill one hole 1 1/4" deep (1/8" bit) or 2" deep (3/6" bit). Sometimes it takes less and sometimes more time than that. I have tried applying the drill with various pressure and have settled on "moderate" pressure. After drilling more than a dozen of these I realized I had many more to do and bought a DCD950 XRP 1/2" Cordless Drill/river/Hammerdrill. (I was under the mistaken[?] impression that an impact driver would be better than the DC725, and the DCD950 would be even better than that for drilling concrete.) It turns out that the DCD950 is not drilling any faster. This is with a brand new DeWalt DW5221 Rock Carbide Hammer Drill Bit. At the moment I am planning to return the DCD950, but I have no idea what to do. I can't afford much more than a $150 tool. Any idea why I am experiencing such poor performance? --And how to speed it up?
