you said the (down-side) of the gammil is your two training sessions?...
i think no matter what machine a person chooses ... part of the choice should include...training.
when i bought my long-arm i did not take that into consideration and the first year was much (rougher) than it needed to be...had i just had the opportunity to take a couple classes. instead i had to do my trouble shooting over the phone long distance.
if i ever upgrade, switch machines one of the features will definitly be (support and training)included.
