This guy is selling a D200 Hugyfot setup but is splitting it up.
$1200 for DUAL Strobe Package
-2x Ikelite DS125
-Ikelite Single Cord (Nikonos to Ike)
-Ikelite Dual Cord (Nikonos to Ike )
- 2x ULCS Arm Sets (Total of 7x Ulcs Clamps, 4x Arms : 6inch & 8inch)
A real bargain.
As to the Hugyfot re: Aquatica. Aquatica have just announced that they are providing a conversion for the D200 housing to allow it to be used with D300s. This means that the market that I was looking at, D200 users upgrading to D300, has disappeared. And the Hugyfot was available now
Forgot to say that the new rig will be available for the Sailing Ship project. In fact, I am hoping to take it to Hemmoor next weekend. D200 body was supposed to arrive today but didn't. Have to wait until Tuesday to play with my new toy
