Sure, I've paid that for some Amigas in my collection... last A4000Towerised one I paid for that amount however had a 233mhz PPC 604e board as well... I run OS4 classic on it... though haven't booted it for awhile... SAM took over...
You pay what you want for whatever... I have around 90 Amiga Systems and never sold anything Amiga... but over the next year or so I am going to start compiling good systems and selling them off... I just haven't got any room any more... LOL
I have two SAMs and I want more... the classic branch will fund the future branch... beautiful ;-)
