In another forum Alexh had a good point for the prices:
(sorry can't remember the title of the forum)
So as he explained after '94 when commodore bankrupted, and there were no new powerful machine, everybody wanted to buy a pc. So everybody sold his amiga. So the prices of amiga hw was low. About '98 when winuae came out, and year by year it worked better, the prices dropped again.
After 2003 the prices continously going higher and higher. Reason: The whole generation which used amiga grow up and get a decent job. Means: We have the money to buy the amiga hw. We're not poor university students anymore witout money.
Last year i had an idea to upgrade my old a500. When i was a "little" child I don't have the money to buy an accelerator card etc to my beloved machine. But now i have. Soon after i get some 68030 accelerator card etc to my miggy, i decided to buy a 1200, because its far cheaper to upgrade. And has more sense. As mentioned above I Higly Recommend to buy an 1200 an upgrade that.
Anyway i love my a500, i has plenty not used 80MB-250MB hd in my cupboard, but i simply don't want to sell. For $10??? or similar why? tell me please...
So now i build and use my 1200 ppc. For the money i spend it i can buy 3-4 ultimate gaming PeCes, but i decide i want the feeling of using the ultimate amiga. Which got a price...
