You are the textbook target for a Colorado. The easy math...assuming you are running Roland brand inks, and being very conservative....you'll save at least $.10/ft2 in ink alone and likely more than double your production speed (if not triple) even when printing in High Quality mode around 400/ft2/hr. If you printed 485 rolls last year then that is a total of 327,375 square feet....now figure you actually printed on 75% of those rolls then you printed 245,531/sf and at only $.10/ft2 in ink savings that puts $24,553 in ink savings back in your pocket a year. If you are printing wall graphics, then you'll be able to sell those unlaminated as the Colorado inks are extremely durable...saving you around $250/roll each (figuring a good polymeric 5 year calendared lam). Lastly - you'll be printing way faster getting your work done in a fraction of the time.
Flexi is just rolling out a Colorado solution, but I'd encourage you to go to Onyx Thrive. Canon very quietly owns Onyx and they have a ton of profiles available for you to use and the list grows weekly. You'll also gain by being able to profile media on your own and as many people on this thread will attest, they can get their ink costs down to nearly $.05/ft2.
I'm a distributor for Canon Colorado - you should absolutely consider talking to a distributor as well as the direct guy. The advantage to buying a Colorado through a distributor is you'll have a HUGE extra layer of support to turn to if things are not working well. Ask any of the guys above about dealing with Canon directly and they'll likely tell you some horror stories. The real problem, as I see it, is their direct guys are not compensated on ink or any consumables, so it is not their fault but they simply move on to the next printer sale...you likely won't hear from them for a few years when they'll be hitting you up to trade your unit in. A distributor will sell you the machine for the same dollars and will be there to help you with your issues...and if they can't fix it, then they can turn to Canon for additional support. Most of the Canon techs don't really know how to address issues with the machine...they just follow instructions given to them by a phone support team. Most of the distributors I know have technicians who can address problems and fix them. I'll guarantee you the other Colorado users here can agree with the fact that some Canon techs just sit there on the phone waiting to be told what to do next for $350/hour.
I'd gladly sell you a machine in Florida, but I'd have no reliable way of supporting you. I know of a very good distributor with offices and techs in Orlando. let me know if you want an introduction. They are also Roland distributors.
