Inon D-2000 vs D-2000S

[alo100]

I would vote for 2000 instead of 2000S, because the price difference is small compare to that 1 shot experience.
I may not want to get Z-240 because of that 4 in Guide Number value (meaning 2000 is having GN 20 and Z-240 is 24).

Z-240 guide number is 24, measured in meters, through air (not water), at ISO 100.
Z-240 offers a hard wired (sync cord) option for triggering. D 2000 and 2000S are optically triggered. If you can find a discontinued D 2000W however, that offered a sync cord option.

D 2000 series strobes by INON all are rated at guide number 20, meters, air, ISO 100.

Any particular preference, bobf?

I'm sure a well cared for D 2000 or D-2000S will hold much of their value if in a couple of years from now you decide to switch to a dSLR that requires a sync cord to send the signal to trigger the external strobe. If however a dSLR is imminent, then the Z-240 makes more sense since it can be triggered both optically or electronically.

I'm not a fan of Auto Exposure. Personally, and unless I'm on a night dive when TTL has proven to me to be more reliable with my particular rig, I use manual strobe control. Although I have never personally used it, I've only heard good reports regarding INON's S-TTL circuitry~technology. The differences between the 2000 and 2000S come down to a target light and Auto. Since I can do without either feature (i have a mini q-40 to aid focus when necessary), I might opt to save the $60 difference and choose the 2000S.

Well said I agree.
