Well I picked up a 430ez, as many canon shooters know only the EX series supports E-TTL, the EZ works with older film cameras with A-TTL, you can however use the flash manually with a digital SLR. I figured I could use it in a strobist setup and occasionally manually on camera until I can afford a new flash. But onen added bonus that I did not think of is that the AF assist beam still functions perfectly with my 20D, so in low light situation I can still shoot using no flash but utilize the AF assist beam and have a huge benefit in focusing accurately and quickly in low light! In some cases I could not AF at all, now it's faster than ever. Just thought other people might find it useful as well.
