I've done some decent $100 kits, so you should find something. The only thing you'll need that you may not have is a 6 gallon carboy. You will need a corker, too, but you can often rent them (or borrow one) from a homebrew store.
Otherwise, you should have everything you need.
To make your life easier, or at least the labor of the kit easier, you could buy a "wine whip". It's a degasser attachment that hooks into your drill so that degassing is quick and easier than hand stirring. You don't need one, but they are very nice to have!
