I don't know any either! I used to have a 500 and 500 + back in the day and well over 1000 disks/games! I am AMAZED at the support avaliable for the Amiga because I thought it was dead and buried to be honest!
I have just got a 1200 and on the lookout for a 500 and 500 + again as well as a 600. Oh it's good to be back in the land of Amiga again!
