I ordered my ft5 last week and was surprised and disappointed to learn i could not upgrade it in any way. I get that it is a kit (as such you expect the buyers to monkey with it) and you do sell upgrades so it seems silly not to be able to upgrade it instead of making us buy things we don't really need or want.. I believe the "hot end" guy mentioned a monster kit version coming some time but the question I have is why would you ever want to discourage a customer from making a purchase? At this point i have parts coming in from as far as NYC, Denmark and China ( i live in Florida) but am getting what i want 1 way or another. I recommend a upgrade price for all parts for instance, want the smoothie board add $40, upgrade sensors add 10 bucks etc. (and you guys keep the extra part so no wasted electronics =win \ win) Clearly business is booming for you all and i hope that trend continues!
