You can always unload the kegerator and change it to ferment temp if you want to skimp (although this gets REALLY OLD really fast, ask me how I know!).
I agree with this if you don't have it. Stir plates are awesome. I suppose this is a gift card? You could get a pound of some neat hop variety for 20 bucks if it isn't, and then make a really interesting beer with it.
I totally understand that at some point, all the big "improvements" in gear you could make cost a lot more than 100 bucks.
