Start with well reviewed SP's. If you start with lower priced from places like Leo's list, you chance getting ripped off and having poor experiences that will ruin it for you. After you've had some fun and been on this board for a bit, you can learn what to watch out for when trying SP's from classifieds like Leo's list. You still might get dinged, but at least you'll know how fun it can be. Some guys really like variety, but what I'm most comfortable with is finding a few you really click with, and sticking with them.
