Well I recently made this very same decision, and my ITP A3 EOS in stainless steel arrived yesterday!
I chose this over the LD01 mainly because it is smaller. I think it is the smallest AAA there is. Also seemed like better value. I got a SS version for less money than the AL Fenix, and you could even get a Titanium version of the EOS for less too.
I chose SS as I think Titanium can scuff more easily.
Very impressed with it. Nice easy UI, three useful settings, seems like a nice quality item, great value.
The clip is trash and the keyring is cheap too, both removed immediately. Light itself seems solid.
BTW, I am Fenix fan, and don't normally opt for the cheaper option, but in this case they just appear to be beaten.
