Though have to agree w/ Robbie on the products they don't qualify for the 'cheapo's. The $15 to $24 ea. is what I consider the cheapo's.
Here's the other version Conti Giro, non-removable valve core.
And a sample of the Clement cheapo. These do have a removable core. Not sure of the inner tube (butyl or latex?) as they slowly leak down.
Old stock (Italy) Vitto Rally. Non-removable valve core.
And for grins, the compromise tubular / clincher. --- NOT TUBULAR ---
