If you want one of those things made especially for bowling (I think Pete and Jeff use an Etonic golf glove), Ebonite makes a glove called the ProTector that has a full hand minus the thumb. It's very sharp -- black cabretta leather with red trim -- and it's not much more expensive than a standard glove.
Also, it has the added benefit of having velcro straps on the fingers, which prevent the leather on fingers 3 and 4 from pulling away and stretching when you throw.
