I don't have experience with DTK, but follow this lead:
I have a buddy that has a litter of nice yellow pups available. Sire is a MH MNH5 and the dam is a MH QAA. Send me a PM if you want his contact info.
Assuming the sire is Mick, and breeder is Frank, you should get a good dog (I apologize in advance if this isn't who is being referenced, just sounds familiar).
Mick is the sire of my new pup, and Frank is good to deal with and has fair prices. I'm sure Kevin with stone-cold retrievers could set up a great training package too.
