If you can afford it I would invest in a female. Prices are always going to drop, but if you get a female now it will be ready to breed in a few years. Males will breed young and I think have some nice morph girls is a good way to go. I don't have a sugar but I do have a pastel calico which is similar. From what I have seen, calicos and sugars do get nicer with age. The white tends to get more vibrant as they grow.
