Just to be clear, that is NOT a 124. It is a simple Yashica-Mat. The 124 has the option for 220 film (12 or 24 exposures- 12/24/- 124) and a meter.
Given that 220 film is almost gone and that the meter is more trouble than it is worth in most cases (e.g. mercury battery issue), this camera is a better option all in all. Appears to be in great shape, and that is a great price. If someone doesn't get this soon, I'll probably break down and give it a new home.
