if you're interested in grape wines, I think a kit might be the way to go. If you're interested in fruit wines, I'd suggest looking at jackkeller.net . Actually, Jack's tips are applicable to any type of wine. It talks about everything from sanitation to bottling. There's tons on there to read, so it might take you a while. The equipment is basically the same as making beer, so you might not have to buy anything except a hand corker, and a few chemicals.
One of the main differences is how to treat your must (wort). In ales, you keep it out of the air. In wine, you encourage air to get to it until your specific gravity reaches 1.020 or so, then you place it under airlock. The higher abv along with campden tablets protects it, I guess. I use a bucket for primary, covered with a dish towel to keep out fruit flies. Then I use a 5 gallon carboy with an airlock for secondary, racking as necessary. I love winemaking, but beer has more immediate gratification. Good luck!
On a personal note, your avatar just put me on a diet.
