We have a Summa D140R as our main go-to cutter and it's served us very well. We've never needed a technician, consistent output and fairly fast. That being said all I can stress is to stay well away from cheap no name, re-badged brands. Stick with the well-known brands like Summa, Roland, Mimaki, Graphtec etc.
As for the printer - I'm a glutton for punishment so I'm sticking with HP's latex presses for now. I know they're more costly, but the damned print quality, immediate workability and no odour just tickles me in the right way.
