Agreed that the best start is a .22, even if you buy it, use it, and sell it. Its very hard to buy the perfect gun for you on the first try. Same is true for fishing gear, pool cues, and knives, etc.
I was in an archery shop the other day, with an old bow, and I asked about arrows. Of course, the guy said, "What do you prefer to use? What will you be shooting?" there are probably 1000 variations of this situation.
After years of getting everyone's opinions, I have become more of a "get one, get some training, build some experience, and THEN ask" kind of guy.
