How to add a 2nd (Nikon) flash

I've just won a cheap SB-24 flash on eBay [primarily to use on my Nikon film kit] and I'm wondering how I might add it to my existing flash with my 450D for more OCF flexibility.

I've got a 430EXII and an RF-602 trigger and receiver so far to allow a single flash to be used off camera. Is it simply a matter of buying another receiver unit, and if so, should it be a Canon or Nikon variety to be compatible with the flash and trigger?

Can someone point me in the right direction, thanks.

Yes, just buy another receiver. I've read that you can use the same receiver for either Nikon or Canon flash.

A hot shoe is a hot shoe is a hot shoe (unless you have Minolta/Sony equipment )

If you're working with all manual flashes, all the triggers should work on a variety of flashes.

Cheers guys, I'll just bag another receiver, thanks for the advice!

I would say the only gotcha would be figuring out the lighting output differences (if any) between the two flashes when using them in tandem. But I am sure you will figure it out with some practice
