Voltage? ;-) Or maybe when they get RHoS they become V and if they are low voltage RHoS, they become LV? Too wacky, especially with those versions that had 'H' added to them to identify if they were 12 clock or 6 clock by default...

They should just let you build the part you want out of the vast list of modules, then price it at the end. Or just make one part with everything in it and kill off all the other parts. I thought the most expensive part was the plastic anyway ;-)
