I was asking myself this questions as well lol. I think a Pastel, Spider, or Cinnamon would be a great choice. You can get each for about $200+, but most Pastels will be under $200. If you wanted a really beautiful bright Pastel, you'd probably be spending over $200. Honestly, I like the Spiders and Cinnamons, but Pastels cost less so if you don't want to spend a lot of money I would say go for the Pastel. They are still a beautiful morph(:

Depending on size, if you wanted a BP that would be around 4 feet as an adult, go for a male. Females are larger than males, but if you wanted one that gets large like 5-6 feet go for a female (:
