Cheaper? I've been lucky enough to have a handful of 32MB FPM/72-pin RAM, but there was time when I was buying cheap PCI Powermacs just to scrounge the RAM for my 9600. It's now up to ~ 896MB, accounting for about six different, gutted machines
Certainly 16MB DIMMS are a dime a dozen, but the EDO RAM is hard to get cheaply, as least that's what I've found.
