I've got the L-358 and use it a surprising amount of the time. I have to say I've not tried it out with flash, but having the facility is why I bought that model in the first place. Have to say that I've learned to trust what I'm being told by the hand-held where I couldn't say the same about the 350D's TTL metering.
I agree with Chris and Mike on the L-358. Some of the Minolta meters are being reborn as Kenko meters, and the KFM-1100 (=Minolta Auto Meter V F) might be a contender. If you wanted spot metering as well it would not be the best choice - something like the L-758DR, which is a combination incident and spot would be better.
Thre's another recent thread on light meters here:link.
Another vote for the Sekonic 358. Great meter that has served me well. If you need to step up later the L-758DR is the way to go. Even if you do step up someday the 358 is a great meter to have in your bag always.
