Sometime because the selection is so huge, you don't know which scipt works for you. For one thing that I hope those scripts/programs database websites offer a demo for each script they have. That way you'll at least get an idea what the script might look like so you'll know if you want to try it out or not. More often than not I have to download at least 10 scripts or so, install, trouble shooting etc. before I know if the script is right for me or not. That simply takes too much time.
