I went with the Valley Vintner one mainly because I looked around and it would pretty much cost me the same after buying the adapters to get down tpo 3/8" for racking hose as most come ready for 1" pipe.
I agree, I looked at the big chain stores and most of them were actually way over the Valley Vintner price believe it or not even after adding shipping in. Walmart sometimes carries them but still I have to search for fittings so screw it. Most of them I see around in the stores are like you said not see through and I wouldnt go for that at all!
Good idea for Wade. You could put together a package of fittings, hoses, and clamps to go with the filter as an option. Everyone likes convience. I bought my vac pump from Wade and then had to shop around for the filter and filter elements, then for the hoses, etc. I think I had part and pieces coming from 4 different places!
