uh-oh... dangerous place to be - contemplating on the website

watch out for GAS attack!! yeah i agree the r2a/m, r3a/m, and r4a/m are great bodies, and i hope Kobayashi-san continues to produce these fine film cameras for a long time. when you feel a Leica in your hand, though, something magical does happen....
btw i actually quite like your 40mm f/1.4. mine is currently on loan to the amazingly talented Sissi Li in London, along with my Rd1s. what sort of upgrade were you looking to do? going wide or to a 50?
