get a trek 1000. since your 17 get a size slightly bigger so you can grow into it a little. find a shop that give you free gear. i know the lbs i go to gave me a free locking system and all the water bottles i need. if you can get the bike for around 650-700 with a free helmet. then get gloves 10-20 bucks, and some bibs 30-70 bucks, and a little saddlebag for under the seat 10-20 bucks, no need for jerseys. and if you need tubes to replace flats the lbs would probably give you some free ones when you buy the bike. and pay cash my lbs likes that.
