OP...this can be expensive but if you shop smart you can outfit yourself for decent prices. I personally shop around for anything. I have had good luck with genuine innovations Co2 inflators. They even carry them in Wally world now. Co2 cartridges, get the generic ones from amazon in bulk and you can get them for less than a buck each. The hand pump I use is a crank brothers with gauge http://www.nashbar.com/bikes/Product...1#ReviewHeader if you read the reviews it has one good one and two bad ones but it's obvious the two bad ones are user error. I can inflate to 100 psi with this any day.

I buy tubes six at a time off ebay for $4.16 each http://www.ebay.com/itm/6-NEW-700-x-...item20d8ea95ba

tire levers are cheap at the bike shop, bottle cages can be cheap unless you want very light and strong. if you just want strong, they can be really cheap. I use Lezyne flow cages ad they hold the bottle very well http://www.ebay.com/itm/Lezyne-Flow-...item51b1f5d46a
