I was late where computers are concerned.
I bought a brand new Atari 130 XE for DM299 (approx $600?) from a department store in Germany, which had it on offer for one week in 1985. I thought that's all you need. Doh.
Week later I purchased a XC11 and a 1050, a Sanyo monitor, and a Seikosha printer (which plugged directly in). So on top of the XE price, another DM 1000.

Year later I purchased a C64 and a 1541, both for something like GBP 500.
