Default External clock for PCM2707

Hey guys!

I'm working on an integrated USB DAC/Tube Headphone amp based on PCM2707 as a receiver and 4/8 TDA1543 DAC chips.

At this time, I'm trying to decide on the clock for the PCM2707. Looking through the datasheet, I take it the easy path would be to simply stick a crystal between XTI and XTO. However,"everyone" seems to agree that the chips internal clock generator is not that good and using an external oscillator would be better. Most implementations talked about either Tentlabs or Crystek, but I found both to be very expensive. Then again, I've found a Vishal Dale version that is much much cheaper (6$ / 4pcs), so I'm wondering if it's any good.

Can anyone suggest any options in between?
