Freakie_frog: it all depends on how patient you want to be, how much inbreeding you are willing to do, or both. First of all, it is usually pretty difficult to find a mature female. If you're lucky, you may still be able to find 2003 females but they are going fast as breeding season is coming up. If you bred him to a normal female, you would then have to raise the female up and cycle her according to your routine. Also, there's no guarantees you'll be successful, which is why some people usually have multiple females (up to 10) for each breeding project. You would then have to grow up all the daughters and breed the father to them once they become mature.

Now, for first generation results, you'd need to find either a 100% het, or an albino female. However, that will cost a fair bit more money, especially if you get multiple females. Also, there's no guarantee that your male is het; a 66% het is only a possible het, meaning he may be a het, but he may also not be. The 66% just refers to the probability of him being het, not how much het gene is in him.

Anyway, if you're serious about proving him out without it getting too expensive, I would personally buy 2 100% het females. At least that way, if you get all normal offspring 2 years in a row, you'll know it's your male that's missing the gene as opposed to having to guess which one it is. Of course, if you just want to breed for fun and don't mind getting normals, just get a 66% het female and take a chance. You'll only have a 44% chance of producing albinos, but it should be fun all the same, and who knows, you might get lucky =)
