I haven't used that particular service but have purchased from Price Japan and also Ebay with Japanese sellers with a good rating. I have had no issues with service and ended up with big savings long as you are okay taking the risk of not having a US warranty. The Ebay seller did offer a 30 day return policy which I did not have to use. Triode Corp does have it on their website that they will not warranty or offer repair service for products sold from unauthorized vendors. In some cases, if your item does happen to have issues, you can most likely have a local tech shop repair it for you at your cost.

Anyone on here ever purchase through this buying service?
