Financial emergency has resulted in my need to sell this strobe. I use my studio strobes for most of my lighting, so I can afford to let this one go, for now. If you don't know the specs, just google them. This model is also out of production now, so that has inflated its price on available stock. I bought it new for 500.00, and I've only used it a handful of times. It still looks pretty much new. I don't think it's had more than 200 flashes. MUST SELL TODAY, and MUST PAY TODAY though. You can send payment to my wife's paypal, but contact me first to see if available still. $280.00 TYD , OBO Thanks all. I don't check here often, so if interested, email me at: firstname.lastname@example.org that goes straight to my phone.
