I just bought my first pair of Hotots at Convention and Patty Percy was recommended to me by a number of friends. I ended up getting my pair from her and am VERY pleased!
However, be careful about buying lines and not the rabbit themselves. Every rabbit should be evaluated for its own individual characteristics. Once a rabbit leaves the barn of a well-known breeder, those breeders are no longer in control of what they're bred to, what the babies are sold as, etc. The name on a pedigree doesn't guarantee quality- the characteristics of the rabbit itself does. If the rabbit is well bred, having that consistent, well-known line behind it is then a benefit because you have the opportunity to reproduce the characteristics of the line with careful breeding.
