True its a risk, eBay always is. Quality RISC OS gear always has been expensive, frankly too expensive for my budget. eBay is only affordable way that I have to buy kit.
Everyone knows the older the memory the more expensive it becomes. Espcially with EDO being as ancient as it is. From my perspective though, I could buy 128MB for my RISC PC for £60, or has I have recently buy 1GB of PC3200 for my PC at just over £70.
Still I love the platform, and get berated quite often by my geekier friends for worshipping what they consider an old, archaic religion
