Well, I guess that I can spill the beans that I got my Dr PC JR from Game Choice Club (www.gamchoice.com.hk); however, I give them a hesitant recommendation. It's a little expensive, but the biggest problem is that they didn't include those valuable system disks with the unit, even though it is listed as being new on their website, and they opened the package to put their "Game Choice Club" sticker on the bottom of the unit. Furthermore, I had asked them to verify with me that the disks did in fact come with the unit before they shipped it to me, and they said "of course". So, really, if you buy one, double-check that the disks are included, and that they guarantee that they will be shipped along with the unit.
Anyhow, GCC should be sending the disks that were promised, but it seems that they are very reluctant to part with them. I wonder why...
