I ordered the 500M from Abe's of Maine last week and it arrived this morning.
Carrier was Rude Transportation Co., the set was not on a pallet, but strapped securely to the side of the truck with nothing around it.
The driver helped me take it into the basement to inspect it. I didn't' see any visible cracks so I plugged it in to see if it would turn on. The set had a LOUD buzzing and then the standby would blink red. I fiddled with this to try and get it working and ended up calling Abe's. They said they'd send a Pio rep out there to fix it at no additional cost (they asked about shipping damage first, and I told them I didn't see any yet). The driver mentioned that after a 1/2 hour he would have to charge me more, so I signed his ticket under the impression that my set would be fixed. Well 2 min after I sign the ticket and he leaves, I go over the set again with a flash light only to find 2 hairline fractures near the top of the set on each corner. So, I call Abe's back and they said to send in damage photos to get a claim started. I haven't heard back after emailing the photos, but hopefully they'll pull through.
Just kind of a big mess right now, but there has to be a light at the end of the tunnel!
