i have. many times. i bought from Chard56 on here many times(i had 5 total from him), and adopted a pair from another user. :B it's a bit stressful on us, the owners, but so far the ones i got were pretty okay with being shipped.
as for finding breeders, there's a few on here(check the classifieds section), or you could check out Aquabid.com
Aquabid is fabulous. Shipping fish can be quite pricy, but if you want breeders or something unique, it's worth it in my opinion! I got my HMPK boy Cirque off Aquabid. He's an import from Thailand, and transshipping and such was actually a very simple process and he arrived alive and healthy!
Oh and now that we've told you about Aquabid...expect to find yourself on there A LOT! XD
Are there American breeders who are maintaining a website or selling outside of Aquabid? I'd just love to have other places to look for the particular fish that I'd like, and at this time I'm not comfortable importing from Thailand.
I realize there are a few American breeders on Aquabid, but their current selections are not what I'm seeking, color-wise.
I bought my blue halfmoon male(one from avatar) from an online breeder..very kind gentleman easy sales ships quick and arrive great..I was told of him from a friend because he sells only (show males) never sells females..so I thought id buy from him and adopt females..and yes he was kind..he shipped 3 females..two dark blue crowntails and a metallic blue halfmoon..I know getting free ones sometimes its because they are cull or not as great genes..but I don't breed and I've seen too many of those horrible culling vids ...(like the chicken farm ones where they don't need males)
O.O got way off topic but he sells beautiful fish around 38 bucks total including shipping from NY..
Edited to make correction(blue male said is not from my avitar its in my albums sorry for error)
