Thanks guys! Great and helpful points!

Will definitely get some samples, I'm curious though, as a newcomer to 3D-printing - How much is 5 or 10 m of 1.75 mm PLA good for, I mean, what can I print? Oh and I just realised that this is a question that is much easier to ask than it is to answer... Maybe be using something from the new matter store and how many of those one could (guesstimately) print
