I have 2 Wein HS-XL super slaves,
1 Wein HSHS Safe-Synch voltage regulator
1 Hitachi Remote eye slave
1 Nikon AS-15
1 Lumiquest Mini SoftBox
The Wein products are useable with standard hot shoe or PC connector.
All 3 slaves also have 1/4-20 threads on the bottom.
The Nikon AS-15 converts any standard hot shoe to a PC connector.

Just the HSHS Safe-Synch sells for $50 brand new
I will sell all of this gear for $45 with free shipping inside the USA.
Paypal only.
Thanks.
