I don't mind buying modded macs as long as they are done with some form of taste...upgrading a 128k isn't really killing it but rather increasing its usefulness which makes sense for the times when the 128k/512k was actively used. A 128k upgraded to a 512k may be a collectible in its own right as compared to a regular from factory 512k because it is not just a 512k but an upgraded 128k mac. Personally I think it'd be neat to have a stock 128k, a 128k upgraded to a 512k and a stock 512k but that's just me.
