I just got the FL-36R version at beachcamera for 175 USD, it turned out to be 5 dollars cheaper than the FL-36 version due to the instand mfr instand rebate, so why not. Even if my camera is not wireless compatible lol. I don't find the recharge rate to be all that bad, just use some good batteries, I used Duracells 2700 mah NiMH.
Ergonomics was also important to me, as I held my sister in law's 400D/XTi with the 430ex flash, and it seemed very top heavy. To the point that prolonged use made my hand started cramping. On the E-510 with the FL-36R on the other hand, it feels very well balanced and I can hold the camera all day long in comfort.
