While Josh has some humorous and sometimes valid points - It really boils down to what you are looking to accomplish with your business and which printer will get you there with the best return on investment. It may be an eco-solvent machine, it may be a latex machine. Both have pros and cons. I have a preference myself, but I would approach the decision by asking end users (like you have here), getting a full personal demo using your own files, having all of the costs of ownership (including costs of print heads, inks, cleaning supplies, maintenance contracts, cost of service calls, etc - Not just a cost per square foot that may include print heads and inks). How long is the warranty and what specifically does it cover and what does it NOT cover. Talk directly to a customer who owns the machine to understand what its like to own. How was the quality of the training, what does a service call look like (downtime), what happens when you have a print quality issue, how does phone support work, how does a warranty repair work? Don't just focus on the cost of the machine, or the latest promo going on. Don't rush into a decision.
All of these issues will vary greatly between manufacturers, dealers and even geographic locations.
Best of Luck to you!
