USPS Priority Mail

It would be cheaper FedEx ground but I like USPS Priority, I figure the less time anyone has my gear the less likely it is to be damaged.

FedEx or UPS Ground will be less expensive. Ground service will be slower that Priority Mail. USPS Priority Mail across the country will be handled less since the package will likely have to travel via air to make the 2-3 day delivery guarantee.

Other than that, there's little difference, IMO.

In my experience, USPS Priority Mail has been more reliable and predictable than any of the other "affordable" shipping service, without question.

I have to agree,,I have been shipping electronics for years and never had an issue with USPS..I can't say that for FED EX or UPS.......What you need to do for insurance with USPS is insure it for double the value...Its cheap anyway..I was told that by my freind who works for USPS...The reasoning is if it get destroyed USPS Pro Rates so make sure you have double insurance...........
