The thing to keep in mind...my three printers are considered moderate in price ($150-200) but all three come with print profilers...which allowed me to almost match David's high end printer ($800). The biggest difference? David's printer uses a minimum of 7 inks...mine blends from black and three primary colors...so it took weeks to match the originals from David's printer. I test-printed and printed until I had prints that almost match his...
Since so many people are making their own decks...the printers that I use are the Epson C-80 and C84. The C84 is new and I still haven't matched up its print profile yet...the software that comes with these printers allows you to create a custom print profile and save it...
The biggest expense (besides the start-up of purchasing the printers, laminator, etc) is the paper and inks. The inks, because of their quality, are very expensive. A black cartridge alone is $32...the color cartridges cost $12 each. With images as dense in saturation as the Portals, I go thru these quickly. And of course, the printers have to be constantly maintained...or you get blotches, uneven printing, etc., etc. David goes through agony with his high end printers...because of both the volume of printing that he does and because those are extremely complex and just a speck of paper remnant can ruin an entire print.
I can't recommend the Epson C-80 series printers enough (and NO, they don't give me a dime <G> unfortunately)!! I use one for basic stuff - LWB's, my general paperwork, office work, and the other two for both the deck and my other work.
The only limitation? Paper size - you are limited to a standard and letter size sheet. But on the plus side? Tons of different papers, card stock, etc can be used with them and the ink is always available somewhere. AND the print software what comes with them allows you an incredible amount of freedom in designing how the color plays out...from something like the Portals to printing your own photography.
I think you'd be pleased with the results and find that the costs of running them are worth it in the long run.
Again, I hope this information helps...I just have been seeing so many talented people with decks they want to produce...and we have had outstanding success and I must say...freedom and control of our product, with the Epson printers...I hope that my experience can allow someone else the same degree of freedom and pride.
