Well Dan today I'm following you LOL Michigan1 to answer your question I echo Dan check out some garage sales, Flea markets, Salvation army, even Craigslist. You can find something real cheap there and exactly what you are comfortable with. You can even check out (window shop) your local bike stores to find what you are comfortable with, and if you like the price you can buy then if not you have a better idea what you are looking for and a basic cost range to judge by. As far as changing them, well that's not hard at all. you can use the references that Dan has provided.
And The only stupid question is the one not asked. If you have questions, we have answers. (where have I heard that before?) Just remember you are asking people who are going to give you answers based on experience, not on text knowledge. Everything we have learned is by trial and error. Yes we are a proud bunch, and we might stick our chest out a little further but we have earned that right here.
Welcome to the forum, and the addiction...Enjoy the ride! =)
