so before i get flamed for "get a sb600 or 800", i know. really i do. but it's much easier to part with $10-20 for "a" flash for now, and get the one i really need later....(and since the 900's are out, i would expect to see everyone dumping their 800's for relatively cheap

).
anyway, to the point. so i bought a $10 (including shipping) flash from ebay. it's some "achiever dz260". well i forgot to read the part that said "for nikon FILM cameras" when i have a digital, but it says it does TTL and i figured a flash is a flash (when in full manual) right?
well i can't get it to work with my d50 (go figure). i set the flash to what i think is manual, and set my d50 to full manual, but the flash won't fire (does that blinking flash icon deal in the viewfinder and on the top panel). i read in the d50 manual that it means the flash won't do ttl and to set to manual. well i did and still just the blink..soooooo what gives?
i've looked online but can't seem to find a manual for the flash. apparently it's some company out of hong kong (go figure, again). i sent an email earlier today and am awaiting their response.
ok, so to recap, i've tried every combo on the flash itself (i was thinking on the front set to ttl m, and on the back m), and tried both ttl and m (thinking that m should at least work) on the camera, but i just get the blinking flash icon. also, the 4 pins on the flash line up with the 4 pins on the hotshoe. and the flash does fire when i hit the test button, so i don't think it's broken...
anyone have any recommendations (except the obvious get a real flash!)?
i was hoping it would be something easy like when i first tried to use a d lens...and didn't know you had to lock the aperture with the switch with the orange dot.....
