I also love my VZ. Lok and pachmayr are two other similar brands that cost less, but I can't speak to them personally.
After you choose a brand, you'll need to choose a style: diamondback, frag, diamond, golf ball etc (those are vz names, not sure if they are the same across brands.) They have recommendations on style based on what your intended use is if you check out their website. For what it's worth, I chose Frag and have no complaints.
