Enter the Kenda Q-Tubes with removable cores. Excellent! They're made of a nice, thick rubber, and putting in sealant is a cinch. Just make sure to clean out the stem once you're done, to keep the sealant from jamming up the valve.
It's also nice that these tubes are made small with the intent of expanding... makes it much easier to mount the tire.
The one thing that I saw that concerned me, is that on one of my tubes, when I took out the core, the tiny o-ring that seals it was sitting funny and had gotten sliced a tiny bit by the threads. I hope this doesn't become a problem down the line. As of now, it's holding the pressure just fine.
PROS: Durable, Removable presta cores
Maybe I got the one in a thousand dud, but I'll never buy another and urge you to save your money.
