if the transport/laser is bad could be $800 ouchThat's ridiculous.

I recently had the laser assembly replaced in my Denon 3910. The part cost $150. Figure an hour of labor.
If your Prima uses the Philips CDM12 transport, they are being sold new-in-the-box on Ebay for $39.
If your Prima uses the Sony transport, it shouldn't cost any more than the $150 laser assembly installed in my Denon.
$800 seems out of line for this repair.
