I am looking for a cheep slave flash (I think that is what it is called) separate unit that picks up the flash from my camera and also flashes unfortunately my camera dose not have a flash connection and dose that irritating preflash are there any cheep flashes that can handle the preflash

any sugestions?

pentax w30

dont know what ttl is but in any of the flash modes the flash goes twice

why dont buy optic flash triger, or radio flash trigger, and use any flash you can find.

edit: i see Leaf already answer similar to my response. sorry for double post. hhhh

ok, simpler question...

what camera are you using?
Can you put your flash in manual mode?

He answered that question already its a simple point-and-shoot without hotshoe. There is no manual mode for the built-in-flash.

If it it fires more than once, maybe the red-eye reduction is on.  Also, some cameras send a bit of light that so the auto-focus can work.  This light doesn't trigger my cheap little slaves, but it does trigger my sensitive studio lights if they are set up as slaves.  If this is the case, can you focus manually?

You may be able to attempt putting a tissue, or a few layers of that white non-translucent office tape over your flash.  As long as it is enough light to still trigger the slaves, you can experiment and come up a good exposure that would be more pleasing than on-camera flash.
