Manuels !

Everything was great, the manual, the response time, the simplicity of the order, and the
Price. The only thing that I could possible say on a negative note would be that the manual I ordered was more for a service tech. There were a lot of schematic diagrams that didn't help me solve the problem. However I would order again and recommend the web sight to others.

I'd been looking for this manual for awhile. Exactly what I needed - and at an excellant price. Thanks!
