Flash for a Super A

I'm looking for a TTL flash that I can use with a recently-acquired Super A for ultra-macro using a bellows unit. Any ideas for a flasgun and off-the-camera lead that won't break the (limited) bank?

The ideal flash for macro work would be a ring flash. Unfortunately these tend to be rather expensive. If you are lucky, you may get the odd one on ebay but still a bit pricey. A quick search on the net shows that Jessops do 2 at reasonable cost. The first is a Centon but this is not dedicated. The other looks very good. It's a Vivitar 6000AF at £69.99. It says its for AF but as it uses the TTL circuitry, I would think it would would work with the Super A. It only comes in Pentax fit and must be a line end. The next ones up are the Sunpak units at £250+. If it works, I don't think you will find a better bargain.
