I have done some research on what I think will work for what I want to do. I am going to buy a 3 stop filter and a 6 stop filter and stack them if I need more. I'm willing to go up to $100 per filter tops. I want to know from you experienced long exposure guys what filters I should buy. I heard to stay away from Tiffen and then someone showed a pic they took with a Tiffen and it was great. I heard the Hoyas are good. I downloaded that free e book from the guys from x filters that showed thier filters have no red or yellow hues like some other filters. So with all this info floating around what should I buy?

Many of the filter manufacturers make different grades of filters... Tiffen offers some very high quailty, as well as series that are much lower prices... and lower quality. Hoya probably makes more different series than anyone else (I think they had six different grades of Circular Polarizers, last time I looked... not to mention that Kenko branded filters are made by the same company). B+W has several different series, too, ranging from their cheapest uncoated or single coated filters in aluminum frames to their best and most expensive multi-coated and newest "Nano" multi-coated in brass frames.
Not all manufacturers make all types of filters in every series. So looking for Neutral Density in certain strengths you might have only two or three from the bigger manufacturers, might only see a single choice from some of the smaller and newer ones.
ND filters, in particular, are designated different ways. For example, Hoya calls their 10-stop filter an "ND1000", 9-stop an "ND500" and 6-stop is an "ND64" (those are "filter factors). B+W uses a different naming convention where "#101, 0.3" equals one stop, "#106, 1.8" is six stops and "#110, 3.0" equals ten stops. Other brands you will find using these or other designations that can be confusing, so be sure to confirm what you are buying.
My thinking is always to buy the best I can, since a filter is a relatively universal product that I'm likely to use for the rest of my life even if I change camera systems for some reason.
First I look for high quality glass (such as German Schott glass) and multi-coatings. Some of the latest filter coatings claim improvements to be more resistant to scratches, dust and fingerprints, plus be easier to clean. I've had good luck with B+W MRC and Nano-MRC, Hoya HD2 and HD3, Heliopan SH-PMC, Lee filters. I'd certainly consider Singh-Ray and others, including some newer brands on the market that are reported to be good. Marumi is one I haven't tried yet. I like the design of Breakthrough's frames, which appear to have deeply carved shapes that might make fitting and removing filters easier and may make them less likely to get stuck on a lens.
Many modern lenses use plastic filter threads, which are naturally less prone to stuck filters. If using lenses with metal threads, you might want to look for brass filter frames that are less likely to stick and gall than aluminum. B+W and others offer a lot of their filters in brass frames.
Price is often, but not always, an indicator of filter quality. So look carefully at the specs.
