All personal accounts and anecdotes, but i’ll share anyway.
My family is an ‘oodle’ family, no doubt. Three of the four we (myself and my parents) have are from animal controls. The fourth was the first one, and my mom feels regretful for buying a ‘goldendoodle’ from a breeder, and spending that much money on her, too! Not really sure why they did that, to be honest. They had standard poodles for over a decade (still had S.Poo #2 at that point), but maybe wanted something a little different, but didn’t want to venture too far from the non-shedding and familiar temperament. Plus a little impulsiveness on their part, probably. Regardless, they got D about 5.5 years ago. She’s 3/4 poodle, 1/4 golden retriever, and a neurotic mess. Sigh. She looks SO much like a ‘real’ standard poodle that it’s just silly. Not that they’d really know how she’d look full grown…
I have two poodle mixes. They both came from area animal controls. Schnoo1 is likely schnauzer/poodle, 30lbs and has a very coarse, thick coat. Less kink than a poodle coat, but similar. Hardly ever mats, which is awesome. Schnoo2 is definitely schnauzer/poodle 15lbs with a very silky, thin, non-poodle, non-schnauzer coat. Her coat mats almost instantly and is MUCH higher maintenance, but i still appreciate that neither shed.
Honestly, I LOVE the combination of poodle and schnauzer, especially Schnoo2’s temperament. She’s scrappy, and a bit of a terrier handful, but smart and biddable, and not too stubborn. LOVES people and praise, rough houses with other dogs twice her size and isn’t delicate one bit. Add to her very portable size and non-shedding and she’s almost perfect, in my opinion! I would love to have another one like her in the future.
Likely, most of my future dogs will follow suit of 5 of our 6 dogs and be from unknown origins (ie, animal control), but i do have some specific breeds in mind that I’d like to own. If I had trouble finding a similar dog in animal control/rescue after an appropriate length of time, and if I could find a pure breed that had all of Schnoo2’s qualities (and looks are included), I’d get that breed (if anyone has suggestions, i’ll take them!) 
I can’t say that i’d seek out a ‘purpose-bred schnoodle’ for all the reasons mentioned, like the price, but mainly because of the breeder aspects. I would only want to support breeders that are reputable- reputable in my mind means a breeder who would wish to improve “their” breed, which wouldn’t imply using their bitches or studs for outcrossing. (I suppose this is more meaningful for the owner of the bitch, since the stud could be collected/used more frequently.) I can’t imagine a reputable breeder would be attaching their names to the “oodle revolution” unless they were solely motivated by money— another thing which negates ‘reputable’ in my mind.
I DO highly adore poodles, in particular standard poodles which I grew up with, and I kind of wish most of these people would just go for a purebred poodle instead of falling for the name. Or, instead, finding a breed that has the temperament and most of the physical qualities they want in a dog, and going with that. OR, ha!, if they have the resources (patience, ability to pick out an appropriate adult dog) to go to animal control and find a dog already alive, in danger of being put to sleep.
But that may be too much to ask from most people!!
sorry for the novel, but something i think about often, having poodle mixes but not having bought them from breeders.
(BTW, my parents’ other oodle mix is a boxer/poodle, who i was fostering. She sheds a very minimal amount and is a fascinating combination of both breeds in both looks and temperament. She was dumped at animal control as a puppy, after she didn’t sell outside of Walmart.)
