I remember paying $499 for a 2 meg expansion that fitted on the side of the Amiga 500. I found it useful for Eric Schwartz animations and to use as a ram disk, since I didn't have a hard drive back then. External Floppy drives were around $200 and I am pretty sure my Amiga 500 Starter Pack that included Kindwords (word processor), F18 Interceptor and one other package (perhaps Deluxe Paint?) was all up around $1,000. My 1230 accelerator card for my 1200 was around $500 and $200 for 2 megabytes of memory due to the earth quake in Japan at the time, all so I could play Frontier the way it was meant to be played.
