I usually have to ask myself if I actually need the app and if I have the time (which I find much more valuable) to actually use it.
There are a limited number of app "categories" in the App Store right now; there are one touch dialers, calendars, GTD, clocks, budget apps, games, weather apps, camera apps, etc. Until Apple changes the SDK, I really don't need anything else. I have my 1-2 apps for each category. There is no need for me to purchase another app from one of the above categories. Sure, it may be better, but I already have a good idea about what is good and what is just a re-tread of an already existing app. Additionally, even if it's just $0.99, I really don't have the time to go through another weather, clock, calculator, etc. app as I already likely know what's in it at this point (due to Apple's very restrictive SDK).
