Personalli I would spend your dough replacing the "cheap crappy tripod" with a decent solid one - better support will improve your shots far more than a flash gun , you can do a supprising ammount with natural light and a couple of reflectors - also if you are in a studio set up you can use cheap halogen work lamps filtered through a plastic milk bottle for a soft light approach.

If you remain resolutely commited to the flash gun approach , check out the speed graphic website for off camera mounts and adaptors etc.
