Is a barebones Sun Ultra 60 worth $90 + $30 shipping? No hard drive (or spud bracket), CD-ROM, floppy, memory, graphics, card, or CPUs... Anyone have any cheap spare parts for an Ultra 60 that would make me picking up a barebones one worthwhile? Also, how signficantly better is an Elite3D-m6 over an -m3? Thanks in advance, Nathan Raymond
