I've had a Cibola for over a year and have been overall pleased with its relative simplicity via turn n go. I'm thinking of adding either a DeLeon or White's M6 as I like the VDI feature that I once had in a White's 6000 DI (analog display). So, my question is posed more towards those who have used both and if they have a preference of one over the other and why? Plus, what would you consider a fair value for a used DeLeon? I've established a range for the M6. Thanks for your help.
