Isn't the battery about 12-13 years old?
I would be extremely wary of buying one to actually use.
It might be interesting to have it framed and put on the wall. In fact, one could have a whole color-schemed collection.
How many different colors were there?
I still have the older brother/sister (?) to the 300, the 505 back in the U.S.A., but I haven't turned it on in 11 or so years.
