6922 Tubes!

Hi everyone, There are many old threads about the 6922, I wanted to know what people are using currently that wont break the bank, ( ie...$150 per tube seems a lot). I need to buy 4 new ones for my phono preamp. Should I just order a set of tubes from the manufacturer (Manley Labs) it seems they like to use Electro Harmonics and they are very affordable, so what does a $100 tube do?? because the originals were pretty nice sounding. I just dont want to overspend on tubes for the unit/system im using them in.  Help.
