Just to jump in on the original question a week late...
I struggled with he exact question(s) the OP raises.
My decision came down to the fact that the job the conturo does far exceeds the quality I can get with iron-on , Fast cap tape , or spray . I already had the MFK700, which was a massive time saver. I am in eastern Canada , and the Conturo and table kit (I bought the fixture, but not the whole table) was extremely expensive -- but i justified it on my own job. My wife is very picky, so the Conturo allows me to match or exceed the cabinetry company's work quality. We had a quote of 55K for the kitchen remodel (admittedly includes tops and some refit) , 18K for our walk-in closet, and 22K for our cottage. I did the closet for 2.8K in material and consumables, the cottage for 2.2K in material and hardware, and will finish our kitchen for 4.2K (for the cabinets) .
My own jobs paid for the machine.
In our cottage, we went with a modern melamine slab door, which really saved money, as i normally use pre-made doors sourced here locally. The Conturo simply has a quality finish that i havent seen matched at any level when it comes to melamine.
So i have 5700 invested in the tool and table , another 900 in the mfk700, and 400 in the flush trimmer. The time saving in these tools also need to be taken into account. I monitored my time very closely comparing to spray on adhesive/ iron-on, and using fast cap trimmers.
I did a comparable job to my closet in 2018. The difference was staggering. it was almost 2 full days back then in edge banding and trimming. With the new tools i figure i can do this in 2.5 - 3 hours.
