So but I don't know what your problem is.
I have built 3 RepRapPro Mendels, 2 were from complete kits bought from them and the 3rd was made using parts printed on the other 2.
I've printed all sorts on them including more parts and other things I've designed and downloaded from thingiverse etc...
They've always been helpful and responsive to my queries the trouble is there are so many people that expect things to be plug and play and who don't put the time in to learn how things work.
