Laserpro Mercury service?

I have an older 25 Watt Mercury laser. Previous owner purchased from Signwarehouse but I see they no longer service or sell these units. Does anyone know or have any contact information for someone to service these units in my area? I am in Wisconsin. My laser is currently running fine but just looking ahead to when I might need some service. Thanks, Mark

Jorlink.com in North Carolina is distributor of GCC lasers.

Ditto on Jorlink, I bought a used GCC Explorer 8 years ago, good resource for parts and info- One thing they have that's one of my prized possessions hanging on the wall behind me is a detailed diagram of my machine's motherboard- invaluable to a DIY'er :)
