I have! They are located in Hong Kong so shipping takes 1 to 3 weeks. Normally I get most items in about 10 days.
They ROCK. The stuff they sell it much higher quality then the crap the Hong Kong vendors peddle on eBay any day of the week.
Also they have been around for YEARS. I used to buy my Nintendo system cartridge copiers from them back in the day used for dumping cartridges to rom files to play on your console with the blank ram based cartridges.
I just bought some Xbox 360 external hard drive cases from them to make some hacked Xbox 360 250gb HDD. The suckers even came with all the right molding marks in the plastic AND they included the sticks that go on the hard drive case (including the holographic security sticker). Can't tell them from factory Microsoft 360 HDD's!
That place sells good stuff.
