I work in Brussel and there is a huge shop named "pêle-mêle", they buy/sell all kind of video games, accessories and comic books. There was a competition pro blue and an adaptor for sale. The bundle was for 25 euros (17 for the stick and 8 for the adapter) or separate for 20 euros the controller and 10 euros the adapter, i bought the bundle.

A workmate saw me browsing for that kind of herdware this morning and, during his lunchtime, he saw one at the shop, he called me and i could order it on the phone... The shop has a website but i'm not sure that all they have is listed on their ebay section. That shop is kind of messy, that's why they are named "pêle-mêle" which means "placed on top of each other"...

Anyway, if you want, i can always keep an eye on what they have and if, one day, i see one for sale, i can PM you and we can manage something together (i buy it and i send it to you). I go there at least once every 2 weeks but my workmate goes there all the time. I had no idea they would have that kind of stuff but if they do again, i'll contact you

PS: If anyone else is interested as well, let me know and i'll make a PM list ^_-
