Like Yamaha used to say different stroke for different folk, I have one and I like it. Once aligned I found it to be pretty solid, but I have the baseboard screwed down to the enlarger and the front cross piece mounted on the table. I also leveled the table before tightening all the bolts and made sure all 4 feet were in contact with the floor. I've not noticed any issues with flex or vibration. I've actually considered looking for a 2nd one for my other 45MX.
