That's what possible het males are going for, about 30. They're basically normals because most people won't take the time or use a female to try to prove them out. Is he possible het Albino, Ghost AND pied? That might be fun, but if you're planning on breeding a visual male albino or ghost at least is pretty cheap (ive seen male ghosts for 150, albinos for 250, and pieds are about 600-800 so not cheap, but still).

Are you planning on breeding?

Most twins i've seen through bp.net seem to catch up eventually. Most males top out around 3-3.5 feet regardless. Sometimes you'll get a nice big 'ol boy thats 4-5 but theres no guarantee on size.
