Heck and I felt uncomfortable after haveing spent about 200 DM (~ 100 EUR) for an unpopulated DKB3128 a few years back.
It sure feels nice to have 320 MB Fast on a real Amiga (DBK,Fastlane,CSMKII).
Though the DKB seems to be a little picky when it comes to RAM-modules. An 128 MB set that ran flawlessly on an MKII was only recognised as 64 MB. I had to play around with a lot of 32 MB modules to actually find a set of four that added up to 128 MB.
