Wow...Zefi added a lot of good insight on the show/breeding side there...simple, but good points. Nice! I second all of that. I've been less involved than she has, but have been in both AKC and UKC show rings. Though I know there are bigger shows, the ones I went to Australia were along the lines of what our UKC shows would be here....as for overall vibes and everything. Some of the larger Aussie shows probably get more like AKC ones. I've never been to a Canadian show, though both my mini's were CKC champions, of all things. I've known many people in the dog world over the years now, and could pretty much get my pick in eskies, and have some inroads with *some* poodle people, but realistically not many. I wouldn't be a complete newbie in poodles if I started with one in AKC, but I'd be fairly fresh meat for awhile. But as Zefi mentioned, when you know one breed, or have been in the world of dog shows in the past, you pick up new things a lot faster overall.
If I were to want to get a show quality poodle at this point, I'd go through the connections I have in the breed. Hopefully track something down I like and go from there. I'd probably go at least UKC and AKC if possible too, to build myself up over time. A newbie in AKC is going to have a lot of letdowns, so that's why I recommended the UKC...because you can do better faster there. And when you learn through positive experiences, you tend to keep moving forward. Instead of never getting anywhere in the AKC.
Though it's great if you want to get into the ring, I'd actually advise any first time poodle owner to not expect a first rate dog, nor top results in the ring. And don't just wait until you *can* have those things....you'll never get them that way. Do your best....get the best dog you can, but realize it'll be a training dog...for both of you. Anyone really wanting to show and do well in conformation will not just have one dog.....they will have a first, then a second, etc. It might not be until your third of fifth dog you really start getting traction, but you have to keep at it. If you do well, as Zefi has done, you can make traction sooner, but she's an awesome groomer and great with the dogs, so she fasttracks to doing well!
When I got into eskies, I hardly knew the breed, but knew I wanted to learn as much as I could. When I found Shelby's breeder, I liked her dogs, and decided to go with one. Sure, I could have hunted longer and further, but I may have only done marginally better. And I knew I'd be learning as I went too, so figured I can get a good dog from this breeder...go for it....learn as I go. I'm still learning!

But I don't regret getting her when I did....I'm sure I'd do it all again the same way. I know better now what I like in the breed, and can be more selective in future eskies.
Similarly, it took me *years* to find things I truly loved about poodles. It wasn't until I was holding Amber one night that realized how much I loved the miniature size. After owning a poodle for 13 or so years, I was still learning! And still am. Though I do know more of what I'd look for in a poodle these days, and am hoping I can get a decent enough dog this next time to consider UKC showing or even more!
So....you don't just want to grab any old dog, but you don't need to be on a mission for the holy grail. Do some work, learn what you can, make connections (all the comments made in those respects are great so far), and go from there. Get your dog, do your best, keep moving forward, keep refining your approach, keep moving forward....etc., etc. Find local AKC matches, shows, UKC shows, etc. if you decide to try UKC, CanKC if there, and keep moving forward.

Like the song "Life's a dance...you learn as you go".
