This is a laser product and like a light bulb they eventually need repair. Remember that your 830 was not built yesterday, but you are lucky. You purchased a product from Wadia, Be patient, they can still get parts for this unit. And even if they closed the doors, and filed chapter something, the absoloute worst case you could get your unit serviced by GNS. (not that Steve is a bad guy either)
I can not say the same for most other CD units that are 3+ years old from other manufacturers that can no longer support product because lack of replacement drives, etc. Then what do you do?
Wadia just annoounced several new products at the CES show. (and they look to be very nice) What would make you think that they would be having troubles?
Your problem is with your dealer finding your paperwork, why would you go and flame Wadia on this forum, These guys build product with the best long term CD drives available, state of the art decode chips and software, and rugged power supplies.
Your have to use your head, This is the equal to saying bad things about your car mechanic while your car is up on the lift. If it was my CD repair facility I would not be in a big rush to repair your unit.
