I have owned all of those listed, except the A1500. The last couple added to my list were the A3000T and A2500, but I gave up trying to collect all models and started selling some of my collection over a year ago. Now I am trying really hard to reduce my collection to under 10 Classic Amiga computers and maybe even 5 or under, but it is hard to see any of them go, even if they are not getting used anymore.
For those of you that remember that I was looking to find a CDTV to replace my dead one, I was lucky (or unlucky if you ask my wallet) to get one of Carl Sassenrath's brand new, never been opened, CDTV's that he sold at the AmiWest 2010 Show. I opened up the case during the show and had Dale Luck and Carl Sassenrath sign the inside of the top casing and got of picture of them with the signed case too. Now all I have to do is track down the rest of the original Amiga team (the ones that are still living that is) to get their signatures too and it will be almost like the original A1000 case that has all the signatures engraved, or I should say molded into the inside of the top case. I doubt "Mitchy" is still around to give me his special signature.
