Sam,
I've used CCG Tack Free in the past. It works fine, but I've found it not to be tack free. As I mentioned in a previous post on this thread, you need to either coat it with Sally Hansen's or get it outside in the sun to get the final cure. I used the CCG light as well.

Over the last six months or so, I've been using a brand called Crystal UV. It is truly tack free as advertised. I buy it from a member on WFF who goes by Silvercreek. I'd highly recommend his high power light. The light is so strong If you don't wand it over the uv cure the cure will start smoking.
It will cost you about $50 to get started with the cure and high power light.
I used it an my salt flies this summer and it held up really well to getting whacked on the beach. I really like his product and don't
really see myself using CCG again.
Here is some info on his product.
