Tin Roof Wines make several with screw-cap (maybe all their wines are packaged this way?). Their Sauvignon Blanc from Napa is pretty good (not Montana/Brancott good, but those don't come in a screw-cap). However Tin Roof wines are in the USD 10 per bottle range. That might be the easiest to find in the US, and worth drinking if you do find it.
