I could not find as much info as I would have liked, but here's a sample of PC owners getting screwed (UK)...initially.But you see prices fall massively, while time almost stands still for ST and Amiga users. Then the consoles begin to creep in as well. Nothing from the AGA period i'm afraid. I'm pretty sure some el cheapo amstrad machines could better the PC prices quoted here.
