Macro Ring Flash Question

Hi all,

This is addressed primarily to K10 users but open to anyone who may have some information. I've been hunting for a macro ring flash for my Pentax K10 for a while now. I have a Pentax A 100 2.8 macro and an urge to slap a ring light on the front of its 58mm threads. A few questions for this well-informed group:

1) Will the old AF 080C work on the K10 without too many headaches? In know it will only be in manual mode with this flash but is it functional without having to jump through several hoops of fire?
2) Does Pentax currently offer any other ring lights? I note on the Boz Pentax page there is an AF140C ring flash. Does anyone have it? Will it work on a K10?
3) Any other manufacturers of ring lights you would recommend?
4) Any other macro flash offerings you are aware of that might work on the K10? It could be a bracket or some other sort of rig.

Thanks in advance. I await the usual flood of great information.

MAcro Ring Flash

Thanks for the heads up Phil. A couple of links here I was unaware of. Looks like an area Pentax has dropped the ball on.

Sigma have said that they don't intend to release their ringflash for P-TTL, so don't hold your breath on that one.
