ND filters

[Norotso]

I'm in the market for a ND filter after not being able to slow my shutter down while trying to capture some water fall action. Is there a difference in variable filters vs the step down style of filter lens? Found this one on ebay that I'm interested in: Hoya Variable (http://www.ebay.ca/itm/Hoya-72mm-Variable-Neutral-Density-3-400-ND-NDX-Filter-72-mm-/360479417388?pt=Camera_Filters&hash=item53ee3f642c)

Thx

I have used this (http://www.ebay.ca/itm/MARUMI-DHG-Vari-ND2-ND400-72mm-AUTHORIZED-MARUMI-USA-DEALER-/230847285152?pt=Camera_Filters&hash=item35bf9207a0) one and I am happy with it. You have to realize that turning it all dark will result in some weird stuff (it is like overlaying two circular polarizers), so I would caution on that. But other than that I am happy with the Marumi. Good glass, and cheaper ....

I had been using a variable with good result until day before yesterday. I found it to be pretty much useless to me on the beach in full mid day sun. I ordered a b+ w 3.0 (10 stop reduction) today from amazon. I will get my shot, now.
