A lot of their stuff is overpriced - and there's some guy on ebay who's been selling those cables for like 6 quid each or something for about two years now. Welcome to the world of Amiga.
[I know a lot of people will say that prices are higher because its a smaller market, but I seem to have seen a lot of people ripping off Amiga users)
Quite often, I find that someone will sell some generic part with the word 'Amiga' beside it, and expect to command 4 times the price. I thought Amiga users were computer-savvy; if so, why do people buy a hard drive with 'Amiga' written next to it for more? A hard drive is a bleedin' hard drive.
