I happened to buy a 27" tube from WM and I'm sold on it.
I went through a few $6 tubes for my 27x1.25" Arayas with Continental UltraSport tires. A couple of weeks ago, after a flat (that happened overnight so I wasn't stranded anywhere), I didn't get around to replacing the tube until late, and the only place open was Wal*Mart, so I gave it a shot. The Bell tubes there were like $2.50. At that price, I bought a couple of 27" tubes so I'd have spares. The box advertised the tube as having "air lock" technology, which I didn't think about at the time. But after two weeks, I am putting MUCH LESS AIR into the tube to keep it at about 106psi. I'm happy with the product. And it doesn't seem to be inferior to any Pyramid or Continental tubes I've used.
