Used their Ebay store for the 500W PSU Shuttle PSU in my computer and seemed fine. Don't know how good their RMA is,however,Ebuyer have an MSI HD7870 for the same price:

The MSI GTX660 is also the same price too. Might see prices stabilise over the next week or so,though especially with all this noise of more price reductions.
