There are definitely great breeders on here of all generations- and that's an awesome thing! I only produce F2s and SBTs- Paige is producing SBTs- but we can fill in every other generation with the other fantastic breeders on this site :D
Shipping is stressful for kittens- that's an honest truth. How stressful? Probably moreso then a quick trip to the vet, but less so then being harried by an annoying newcomer all day long (like if you brought home a new puppy!). The thing is- MOST kittens will cry when they initially get into their carrier, will cry when they get dropped off and then will curl up and sleep the flight- only to wake up when they arrive. Kittens and cats sleep 80% of the day anyways- so the carrier turns into a long nap for them until they reach their destination.
For those who can pick up locally- I think it's FANTASTIC. I love people who can drive in and pick up, but to be honest- I think it's easier for a kitten to have a 6 hour flight versus a 12-14 hour drive if need be. I also love when people fly in, but to me- reality is, a lot of people find it hard to fly out and price-wise, I do think it ends up being a bit more to fly in, pick up, and fly out (even in a popular tourist trap town).
Just keep doing your research and when the right kitten comes along, talk to your breeder and see what he/she recommends. I know I've even had a kitten hand delivered to me- loved it! So there are many, many options!
