Yeah... Definitely looking forward to rhat. Got to choose a good yet affordable strobe.
Inon S-2000 seems to be well-regarded, but I have no personal experience with it. Sea & Sea YS-01 is broadly similar. With the release of Inon Z-330 and Sea & Sea YS-D2, the previous models (Z-240, YS-D1) are frequently available on the used market. I thought I would save money by going with SeaFrogs ST-100 Pro, and I somewhat regret it - they have a number of glaring deficiencies that are not advertised; in the end, I have pre-ordered a pair of the new Retras which I hope to have by next year's autumn holidays.
