Ya, I've paid plenty for pc parts in the past but can't beat any of the stories here. When I bought my first PC in 1993, a $2100 486dx250, I do recall part of the costs were a $150 upgrade from a 14.4k modem instead of 2400 and close to $200 for 8 meg instead of 4 memory.
Regarding digital camereas, in 1998 I paid $1000 for 1 megpixel Nikon Coolpix 900, the first real consumer digicam in my opinion and similar to polak187 above, I paid nearly $300 for 48mb flash card.
