I thought I would share my experience with ensquared insurance. I shopped quite a bit to find this deal.
I paid $112 for 2 years coverage on a DroidX I purchased from Verizon 10 days ago. This is slightly more than squaretrade with the slickdeals coupon, but it includes coverage for lost and theft; squaretrade does not. Deductible is $75.
The ensquared site has a calculator that suggested I would do better at Verizon, but I think that whole web app is an add for Verizon/Asurion. I declined Verizon coverage at $8/month and $90 deductible.
The site has the fine print available for download before you purchase. The experience seemed pretty straightforward.
