Sounds like a great plan! I personally prefer Super Fires to BELs, but of course you more often than not get a "cleaner white" snake with BELs. It's all about personal preference. I just can't get over those piercing black eyes with red pupils set on a gorgeous white background.
Good luck finding what you are looking for! 'Tis the season of babies!
EDIT: Also, I realized your original post said you are only looking to spend a couple hundred at the show. You may be able to work out a deal on a male for $200, but not many are that cheap.
