The biggest problem with inexpensive roller laminators is roll handling. Without supply and/or idler roller to straighten out the feed path, misalignments and wrinkles will plague you. They sure plague me, but I've rigged some low tech "bolt-ons" to my laminator that get the job done with a lot less grief.
Hot lamination has an additional advantage over cold -- you can align and sandwich everything before it goes into the laminator, because heat activated adhesives are low- or no-tack at room temperature. That doesn't mean it's a no-brain solution, but it does mean that you can spend some time getting things right before sending it through the machine. Cold lamination requires perfect alignment first time.
If you're not laminating anything bigger than 16x20, you might consider an inexpensive flatbed hot press, something by Seal perhaps (I've got a "frog" that's at least fifty years old and still going). With the right choice of materials you can mount and laminate at one go. There are bigger flatbed presses and even fancy "hot glass vacuum " presses, but they're very expensive and take up a lot of floor space. Still, compared to a wide format printer and as part of business expenses, they're not completly out of line.
Have you tried talking to DryTac directly? They've got technicians who are actually very helpful in making a decision on materials and options. Since they sell both hot and cold adhesive material, they're not predisposed to an answer either way. Give 'em a call and see what they say.
Now, there are other ways to get durable textured prints. There are canvas and linen textured papers, and with an overcoating such as Premier EcoShield (waterbased hvlp spray, gloss/satin/matte avail) you can drymount or cold laminate your output on hardboard and coat them and still enjoy a measure of abrasion and UV resistance.
I'm constantly experimenting with different combinations of media, mounting and protection. One thing is relatively constant, though: I'm done with glazing. Hate glass, hate acrylic, sick of putting prints under it. I'm experimenting now with tapestry printing for a very unique look; some of these prints (at eight feet tall) will be used in our local symphony hall.
Sorry the topic's wandered... There's lots of folks who will have more suggestions for you. Best of luck!
