well most mt2 tooling i got it from ebay and so far i had no problem with it and the quality of it was on par with the mill
as for tearing down mine did not need any as all ways are grounded are are as flat as it can be
as for tooling i highly recommend you get carbide endmill they make a huge difference in the precision of the cut and in the long run the amount of material you will be able to cut without it needing resharpning, anyway its my opinion and mostly if you intend on doing steel and stainless
as for conversion here is a wonderfull conversion that turn out at the end to be a full conversion as the mill cannot even be called a vario anymore but its still interresting
