Nearly 800 bucks for the c64?
My God! That's more than I paid for my original c64 and a the disk drive back in the day - brand new.
More than I paid for my SX-64.
That's just insane! That was the only product I had even a passing interest in, but on seeing that - it would probably be way cheaper to try modding an old case and keyboard off ebay and filling it myself.
