Although you may only need the 30" now, in no time you will wish you were able to print a full-bleed 4x8. I listened to others in the same predicament and opted for the 54" model right out of the gate and have NO regrets on that part. I do, however, sometimes wish I would have considered the JV3 as they seem to be a more robust machine. Still, I've made plenty with my 540V and would never consider a smaller machine now. No matter what anyone says, you need to laminate your prints...whether by hand or with a proper laminator. True, the inks are "rated" for 2-3 years, but they are NOT rated for abrasion or chemicals...unless you can say with absolute certainty that your prints will not be subjected to either of those (yeah, right). I don't laminate every print (or any banner for that matter), but the majority get it to ensure longevity. I've had my machine for going on 17 months now and have used 3rd-party inks from the beginning as well (Triangle MLD). They are a bit better than the Roland MAX inks and are vastly better than the original Roland inks that were the only ones available when I got my machine, plus the bulk ink system is about 60% cheaper than OEM inks.
