Check out 9-speed stuff on nashbar.com. $139 for 105 brifters or $129 for Tiagra. Braze-on 105 front derailleur for $15. $9 off a Sram chain. $7 off a 105 cassette. You could put a nice little order together. There's usually a web coupon in effect as well. A rear derailleur would be fairly easy to find on ebay.
