I own and use the Phottix wireless remote I bought on eBay for like $27. They make a newer model named "Cleon". Plugs into the 10 pin socket, works just fine. Ships outta Hong Kong. For less than $50 its hard to go wrong.
All kinds of choices over at DealExtreme and their prices usually can't be beat and that is even before you factor in their free shipping to most of the world. If you are not in a hurry score something there and expect it at your doorstep in just under two weeks.
I got an endless stream of security windows trying to go to DealExtreme. I couldn't shut down my browser normally. I ended up going to Task Manager to end the program. Be careful of going to DealExtreme. Joe K. Schertz, Texas
