Do you mean HKFlix?
(mods might want to fix the title)
They have been a pretty great company to work with. Fast shipping and good selection. The owners seem quite nice and I've heard a number of great stories about them going the extra mile to make something right (if there is a problem).
Thier prices are a little high, but it's what you get for taking the risk out of importing the titles yourself. Although, their sales titles are often priced below what you can get the DVDs for on Ebay, so I guess it depends on what you are looking at.
You can do a search here and see quite a few people mention them from time to time.
