Honestly not jumping down your throat OP, but your friends breeder with definitely not be affiliated to the KC. To be a KC registered breeder, you need to have a KC registered breed, which a cross breed is not, it's a cross breed 
That said, there is some debate as to how much KC registration means in reality so choose carefully.
Cross breeds wrapped up in designer labels are very 'en vogue' at present so choose the breeder very very carefully, as there is a higher likelihood they are doing it for some element of profit. A good breeder would breed not for profit but to ideally gain a puppy for their own purposes and certainly for the ultimate benefit of their breed.
Again, not saying that some KC registered breeders are doing it for 'pure' reasons, but, add in the 'fashion' element to the mix, and I think it gets harder to find a good breeder. For example, Google Springer Spaniel puppies, then Google Sprocker puppies. Alarmingly, not only will there be 5 times as many Sprocker's, they will be 5 times the price too, which illustrates my point.
Champdogs has a good section which breed descriptors on it, shedding, exercise requirements etc. as does the KC website itself, but won't cover cross breeds. Both have good sections about how to chose a breeder too.
As others have said, rescues also have puppies.
Have you considered a Cocker too? You could always keep him or her clipped short. Our Springer has a full clip (much to DH's disgust, he kind of looks like a dalmation with sawn off legs!), but vastly reduces (mainly) mud, but also hair. Tbh, I don't notice him shedding all that much anyway, grooming is minimal, mud is maximal 
Good luck.
