it depends on which type you prefer. the czech is a bit more hyper than the german lines, but compared to the malinois it is a lazy couch potatoe. you can easily find a great quality dog that is exactly what you want (or as close as possible) in german working or show lines, czech working or showlines.
when you ready to seriously start looking for THE dog, contact rinus and he will find it for you. it may not be one of his, but he knows a ton of breeders and trainers and has 1000 times as many connections as I do. when I got strider from him he didnt charge me shipping, from belgium to louisiana. and I had almost decided on a different dog when he told me about strider (dior van corsalabroek is how Rinus knows him), the other dog wasnt one of his and he wasnt going to charge me a finding fee. a lot of kennels, breeders and importers charge a finding fee which can range from $500-$2,000 or more. he wont steer you wrong, try to convince you to get this dog when you really want that dog, and he wont overcharge you.
