that burm you have is a nice one, very lucky
I like the regular albino's alot more than the granite albino's,so i can see the price being cheeper, i like regular burms better than both of them as well, and green...well they are almost as nice as granites IMO,a few years back i seen a reg granite selling for $400 i emailed the guy that had it and i was a couple days too late
i seen a few on different adds across canada over the years, but i would only send money to a breeder with a good rep not just some craigslist add.
