Thought I might introduce you to my number 2 flash - It's a YONGNUO Speedlite YN 460. Got it off eBay for next to nothing about $70 all up. And it comes with a defuser, and a Minolta/Sony hotshoe adapter. Not a bad deal huh?
Anyway, ever since I got this, I've been practicing my 2 light shooting, of course battery permitting.
