2filter is a great place really, other than the 'not in stock' thing. Call them and if it isn't a rush they're super helpful and really good at helping with issues.

There are threads here on what to get, but you'd have to search to find them. Try that, but basically, go for 2 and 3 stop hard and soft lines, you'll be set then.

Which specific size to get depends on your lenses you'll use and their focal lengths (and whether your body is crop or not).

So far I've only used my hard lines, haven't used soft yet. I'm not sure which is more useful overall, but for me its been the hards.

if anyone can chime in about tiffen's ND filters, they have a bunch on sale at amazon right now: http://www.amazon.com/s/ref=sr_nr_se...%3Aelectronics

My advice is to go with the Cokin filter holders and filters, so that if/when you change lens diameters, you don't have to go out and replace all of your filters - just the filter adapter ring. IIRC, Cokin just makes two different series for different lens sizes (I don't remember offhand what the cut-off is between the two series).

There are actuall a few different sizes.

I went with z-pro's which are 4x6" and work with my sigma 10-20mm. You just need to figure out your widest lens and then research if it'll work with whatever size you want to buy.

I've got a cokin holder and hitech filters.

This is a write up I did with info to a blog that explains the hell out of grad ND's

Just ordered 2-stop soft and 2-stop hard filters with holder from 2filter... I'll use those as a jumping off point to see if I need any others.
