WOW!, I know it's a good size board and all but if it's packed great I'd go ground service and save major money. It still has to travel as far and it's not going to be handled any less or pampared more with two day shipping. Just something to think about.
103.4 lbs stripped weight of the board section,...
with the power supply being another 20 pounds or so. That's HEAVY!
$230 for 2 day delivery seems reasonable, considering the weight. It's beyond the normal weight limits of UPS delivery, I think. It may take special truck delivery, (moving company).
I got an M520 shipped from Arizona to California for about $114, about 18 months ago, delivered by truck. That's just one state away. Cross country would be more.
