spyder is reasonable for its price... but if you want best-bang-for-the-buck, if you don't plan on using it alot, it might be good to just rent one...especially for LCD screens which don't need to be calibrated a lot...
forget the GM one.
i was using that previously.
it just couldnt work on my 27inch monitor.(dunno why)
i got the spyder pro from cp.color looks ok(imho).
i think someone mentioned it's overpriced.
initially wanted the GM color one or two or dunno what but sgp agent no stock.have to order and wait 4-5weeks.
