where to start?

I am a long time pet mouse keeper though not breeder (yet). I have bred and exhibited other pets successfully over the years, but would like to have some show type mice...as they are so gorgeous, with a view to exhibiting them at some point. I have a big empty, insulated shed with power and lighting, and no mice to put in it at the mo!

I adore the BE creams, himi's, siamese, lilacs, blues, brokens and rumpwhites. And also the stunning Astrex. I love the big earred, chunky show types and would very much like a couple of trio's to begin with and see how things go.

I hope to hear your ideas, advice/suggestions with where to start!

I have recently bought 3 young siamese girls (pet quality) from a friend, who has been hobby breeding this line for years. So no known health problems. I would like to have a buck to use with them, but what colour would be best, and who should I ask.

I live in North London, not far from the shows at Enfield.
