Are you looking for makers or just trying to get an idea of styles? If you're just looking for styles, here's the Galco site. http://www.usgalco.com/ Let us know if you're looking for makers .... and be ready for a list a mile long.
By the way, is your Z06 a C5 or C6? I have a C5 convertible.
It's a C5, 2002, the new ones are out of my range. I only have 21,000 miles on it and it's like new without a payment book! I had a 1999 and it was plenty fast that went underwater in hurricane Wilma. When the ZO6 came along I had to have it LOL. They are fun!
