i've had a commodore 1084S for about 3 years although the monitor itself says june 1991 on the back sticker. it is still going ok, although it seems to get pretty hot after just half an hour of the power light being on (whether this is normal for these monitors or not i dont know) and a friend of mine has a similar monitor although his power switch is at the front, so whether on later models commodore put the power switch on the front, or whether its just his being a slightly different model i also do not know. but i have had no colour problems whatsoever (except for that time when it accidentally got hit onto greenscreen ;-) )
