Which TTL flash would you recommend for a Canon 5D mk1, with plninnag for a 5D mk2 IN the near future? I'm rather overwhelmed with my fully-manual Yongnuo 560 mk2, and am currently considering a used Canon 420EX for $115. Guess I could just save UP another hundred for a Metz 44 A1 or Nissin di622, or even a Canon 430EX (NOT sure which one), but I'd rather get one that's more affordable. Unless I'll be unsatisfied and want another upgrade! Recommendations?
