Guess I missed the value train last time I price checked my SAM 440ep complete machine. Paid a grand for the mobo/ram and OS 4.1 back in 2008 and earlier this year the best offer I got on it was 200 euros if I was willing to cover shipping to England for the whole machine, including case, PSU, and the 2 SSD's and 1 SATA DVD-RW that are in it.
I resigned myself into simply using it as a doorstop a few years down the road versus taking such a financial beating on what still is a a pretty fun little machine. Couldn't even find anyone to trade me a decent "legacy" Amiga like an A3000 or A4000 for it :/
I imagine the X1's hold their value far better, but I've seen the SAM boards at basically giveaway prices compared to what people paid for them new.
