I've found Drum City Guitar Land in Colorado to be great guys and very good on prices (I ordered my 20th Silo from them). They've had a number of Y2D's in stock over the past few months that have tempted me.
E-mail MM Customer Service if there's a specific combination you're after and they'll tell you exactly who has it at this time. If price is the biggest factor and you don't mind waiting, give DCGL a try.
