Looks like a cool little machine. Not sure how much the creasestream costs, but you may want to consider heading to ebay, a used equipment dealer or a print equipment auction and looking for a good used Morgana Digifolder. They do a lot for a small shop in a small amount of space. You get a true matrix die style crease and can also fold in line. They are easy to setup and fold many different configurations. MK1 is the oldest slowest model, 5000P is next and the newest and fastest is the "PRO" model with touch screen setup. We have had several over the years and they seem built extremely well and have been very reliable. If you look hard enough and are willing to deal, you can usually find an entry model in the $5000 range.
If you just want to crease and perf, Morgana has machines called autocreasers that do just that. But for the price difference, it's great to be able to do all those fold types in line as well.
Guess it all depends on your volume and budget.
Best of luck!
