albinos are abnormal looking, thats generally what makes them move "valuable" as they are uncommon. they are real popular with other reptile breeders. many garter snake breeders love the normal ones more than the abnormal ones. I love the abnormals, they are neat and with proper care and outcrossing, they can be fun snakes. I really do love the normals. when I was a kid looking thru the field guide to western reptiles and amphibians, I loved the garters! those were the ones I wanted to have...well, all of the snakes, but mainly the garters =)
it's all a matter of personal preference, but I have found that a lot of garter owners love the normals =)
