We've used Vishay 534 series 10 turn pots for 4 out of the last 6 years without any problems or failures. We typically use 5k, except for last year when we used 10k connected to the Jaguar. They are $10-15, which is about the same as the equivalent Bournes.

Any pot is most linear in its center range. We typically try to use no more then 80% of the pot's range.
