Anybody here use uship?

I need to ship some rather large speakers from Va. to NY. I got a quote from a shipper on uship that is very reasonable. However, the cargo insurance uship provides is capped at 2500.00 and the speakers are valued at 6K. The shipper has been on the site for 14 years and has a 100% positive feedback rating with 350 completed shipments.

What say ye?
