On a side note, find a way to lube the window guides in the doors (both sides). The felt gets dry and can actually grab the glass causing the regulators to break even faster than they normally do. Stick with a "dry" lube as you don't want wd-40 or silicone all over your glass. Lube every part of the guide you can find while the door panel is off (inside the door and outside where the window rides). Bet it might even speed it up a little. Oh, and if you ever have the glass frozen in the winter do NOT attempt to open the window until you heat the inside of the car up really well. Even if you scrape the glass on the outside the glass is likely to be frozen to the felt guides and weatherstrip still which will kill the regulator in a heartbeat. Trust me on that one, lol....
I just replaced my drivers reg./motor today again. Went with the Dorman one. I also grease the new regulator guide (the metal part that the cables attach to) before they go in. You can see where the plastic guide rides on the regulator when the window moves up and down, so just lube the sides that need it. I got 3 years out of my last one.
