They are similar to the free standing Aladdins found in a lot of minilabs, they may actually use the same paper. You could try a couple images to see if you are happy with the results. The results are good, but not quite as snappy as a good frontier print. They also are a bit more finicky to set up and keep running well, a donor change almost always is a noticeable color shift requiring a calibration. It's also the size of one of those self serve copiers found in Staples etc. not really what I would call portable. Moving it around would not be a great idea. It would take two men minimum to lift into a truck and I think things would go out of adjustment with constant movement.
What is your need anyway? A Frontier 330 will take up to 8" paper so if you don't need 10" prints and can live with the slower speed it's about 60-70% the price of the 370. However, if you're not going to run a minimum of 20-30 rolls a day through it you will have problems keeping your chemistry good. If what you need is a portable or semi-portable unit for making enlargements I would go with an Epson 2200 or 4000. That, with a fast computer would cost you between $2500-$4000 US, the print costs would be less then the Pictography and it would be portable(ish). If you do try to find an Aladdin to look at the prints, make sure it's a free standing one. Some are hooked directly to a Frontier.
