I am thinking of letting go of my 924122 that is in excellent condition and keeping the 921045 that is still new. (It hasn't even been assembled).I don't feel that the 921045 is the same quality as my older 924122 but I'm getting on in years (72+) and the 924 is a big, heavy machine. I essentially rebuilt the 924 about 3 years ago and it's had little use since then. Anyone feel like sharing their thoughts?
