I've bought from Sonic before and only had one product mess up on me which was a amp. Needless to say I called and emailed them, was told to send it back, and they sent my a replacement all within I'd say a 3 week period which most of was in shipping.
Don't know which to tell you to buy since I don't know how much money you have to spend. If you can afford to spend the extra then I'd say get it with the longer warranty from Sonic.
