I got my craft robo last year, I’m still learning, but I have used it a lot for scrapbooking, so easy to just type your word/sentence, the press cut! I’ve also cut decoupage sheets, and aperture cards.
Not yet got to grips with it fully, something I intend to do this year.
I had bought myself a Bigshot, but found the cost of dies prohibitive, and then sometimes you only want to use the die once (maybe someone should start a library of dies - you can borrow and then return them!) I had balked at buying a robo at first purely for the cost, but when I worked out what I’d have to spend on alphabet sets etc then the robo seemed like a bargain.
There is now some new software for it called Design Master, that allows you to cut welded text, and do all sorts of other things. There are also lots of free templates for it, ukscrappers is a good place to start as they have a craft robo forum.
I think you have to have a serious think about how much you’d use it, it is an expensive piece of kit, but if you are a serious card maker then it will help make your life easier.
