Hi Lisa,

I would not agree that MJR machines are generally not reliable. I have
been using PTC100s for several years in different labs and never had a
single problem with them. I don't know whether this holds true for the
PTC200, but I personally do trust MJR and would by there machines any
time, if the price is right ;-) (usual disclaimer apply). I don't know
the other machines you mentioned.
Hope that helps,
