I hope you were able to find one. Were you? I'm not currently selling mine yet, but I do need to find time to use it more... plus I have cap kits on my backlog of fun mods to do.
I have a Woz edition with CFFA3000 in it, the RGB monitor, the works. Though I have more nostalgia for the OG Apple II and Apple IIe models, the GS just made more sense to me at the time. Buyer's tip: One thing to know with the GS (I forget if this applies to other models) is if possible, find out the Rom revision before buying it or see how readily available and easy it is to update it. Some machines can do ROM 03 whereas others with ROM 00 can only upgrade to ROM 01... that is unless someone in more recent years created some new gear or method that 'fixes' that hurdle.
I hope that helps if you haven't gotten a IIGS yet... that and, the CFFA3000 is truly amazing!
