I hate to admit it but I have 14 machines--shhhh!
Most are vintage that I've picked up for the price of free or up to $35. (except for my little FW)
But my Janome 9000 memory craft is the one I FMQ on 99% of the time. I've had her over 13 years. Bought her new and have never had the slight problem where she's had to go to the dr.
Sewing machines aren't "one size fits all" so I applaude you for doing research. Before I bought my Janome I did that too & tested a lot of models & brands. The only thing I don't like on her is the embroidery. I bought a Babylock Esante several years after getting the Janome 9000 because the Janome was just not "user" friendly for me.
Good luck
