id say go for it. the seller has like 2000 positive feedback. its also "collectible" used? thats why its 60 off.
I bought my acoustic guitar off Amazon. It's absolutely fine.
Yamaha F310 acoustic
Ibanez RGR321ex
Peavey Vypyr 30
Yes, I have used amazon for about a year, and no slip ups on their part have occurred.
Check the SELLER though, remember. Amazon is just a market place for sellers to group together, a bit like Ebay. But far more reliable.

Check the seller like I said, check out to see any problems the customers have with the company (If any). And if you like 'em, go for it.
