I have the Sprayborg and it is a good machine.  Handle folds down if you want to put it in a smaller vehicle.  I also have a 
Trinity Phoenix.  Both have good build quality but the 
Phoenix is faster.  Both use the same 2.5 gallon jugs.  I prefer that over a fixed tank like the Cimex or the Vibe.  With the fixed tanks, you can run into problems with foaming when you try to refill them.  I have over a dozen jugs which I fill at my shop prior to going to the job.  On the highrise buildings I do, I can usually get 3 hallways done with one jug.  Sometimes more.  If I was going to buy another machine, it would be a 
Phoenix.  I sold my Cimex machines after buying the 
Phoenix.
