Seems a shame to get rid of a collection, but if you need room for something else then I guess it has to go. I hope you don't regret it a few years down the track.
When I was at uni I sold all my VZ200/300 gear for similar reasons. A few years ago I looked up VZ200 on the web and discovered a number of resources. I have now managed to build up a decent VZ200/300 collection, but as I am not moving home too often I don't have to drag it around with me. I am setting up a table in the shed for display, and one of the cupboards has the rest of the gear.
Still, with C64 stuff there is plenty of it around so if you ever want it again it will be easy enough to get hold of.
I don't remember anyone else on here mentioning that they collected micros apart from Marty Machine.
