I owned the Spyder 3 Elite and replaced it for a i1 photo LT (munky came out 3 month after !) because i quickly realised i needed printer CM as well. If you want your prints and display to match exactly it wont be easy if you calibrate only your screen !
So, if your printer dont have an integrated profiler, dont make the same mistake as I did and buy something that can profile both even if your on a budget. It's cheaper this way in the long run.
Look for Munki or Spyder print package. There is plenty of comment about both here. Keith Cooper have reviewed both and posted links here.
I need to do free publicity for Xrite as i had great service when I had to exchange some mail with their customer service for an upgrade kit. Quite rare these days that sellers make clients feel like there not a burden to them once the sale is done !
