For your consideration, here is a Sunpak Digiflash 3000 Digital TTL Electronic Flash Unit, made in Singapore.  I have tested it.  The ready indicator comes on.  I did a test flash and it works fine.  The battery compartment is clean.  The flash unit has very little wear on it.  The flash rotates down to 90 degrees and rotates on the base, side to side.  It will be mailed in a box for protection.  Item pictured is the actual item up for sale and comes from a non-smoking household.  (370.319s-.12bb)
