Does not matter if Kaypro's are currently worth average $30.00 in eBay.. In 2010 they may be worth $300.00, and in 2100 they will truly be a museum piece for display.. Yes there are still many in circulation, but as the computer collector population grows they will become less available and therefore more valuable. I also feel that eBay does somewhat reflect or give an indication of market value. True Osborne 01's sometimes go for $600.00 on eBay, but these are usually purchased by someone (Like you said) for pure sentimental value.. However the average price is around $100.00.. So that is what I consider current market value.. Also does not matter if you get one at the local Thrift for $5.00, like I did, they thought it was a Portable Television.. A good example of a mass produced computer may be a Radio Shack Model One, These computers were everywhere in the Mid/late 80's , as PC's took over people began to throw them away. They were worthless to the masses.. Now in 1999 you have to really search around to find one at least in SW Florida.. I will take a guess and say 75% of all the TRS-80 M-1 computers have been thrown away.. The remaining 25% are in the hands of collectors, and as the computer collector population grows so will the value of the limited units available.. The exception may be the Commodore 64 computer. In the year 2100 (I am convinced) people will still be selling these things at Yard Sales.. My guess is that there is still at least one of these units in everyones closet in 1999.. <Grin>!!! Phil...
