Seal quality question

[BrianG]

I am in the middle of going through my front (Dana 44) axle assembly. I'm doing a lot of work on the ends of the axles and thought that I might as well change the inner seals as well. After calling my local Auto Value parts store, they have all of the seals in stock. They have both the "Parts Master" and "National" seals. The salesman said they sell a lot of each. The "Parts Master seals are only around $4 each for the inner's and the pinion seal. The National's are between 3 and 4 times as much. My question is, is it worth the extra money? has anyone had experience using the Parts Master seals. I've used National many times before without issue, but sometimes wonder if I'm just throwing my money away because a lot of times, I know the store brand are made by the big companies. I'm just trying to control my expenses in a sensible way. This thing seems to have a straw attached to my wallet lately, and its sucking up all of my cash!
