I know your question has been out there for awhile, but if you are still checking, maye this will help. Do you need b&w or color? If you are doing decals, you will probably want a laser jet rather than an ink jet so water will not wash off the ink. If you are doing b&w, the hp LaserJet 5100 series printer is a good lower cost machine if you are working in a CAD environment and have relatively low volume. If you would be interested in a used machine, I suggest you try Landmark Pinters at:
The have an extensive selection of refurbished HP LserJets and attractive prices. If you are looking at doing higher volumes of printing, they also have the 8000 series for about $1,000 and it is a work horse. Good luck.
