Yeah Ive used them there OK service. If you go into the shop be aware that you dont pay the "web" prices, in other words they charge more from the shop than the web.
A mate of mine had a bad experience with them a few years back - ordered some DDR3 Corsair dominator ram and received a couple of generic heatspreader-less sticks or DDR2 ram. Eclipse refused to admit they sent him the wrong product, and he never got an RMA or refund. I'll admit he's hardly the most diplomatic person i know, but still. poor show from eclipse. They're reviews on google aren't high, although tthere are only 36...
they're just down the road from me, prices are iffy along with the service, if you go into the store be prepared to wait, the service time is terrible
