Well - you can look at it this way - you pick up a male pastel $500 now breed him the next couple of years to some normal girls maybe pick up a pastel female - make some money and test the breeding waters maybe buy some more expensive morphs, etc. Or you can spend $700 on a pair of het albinos or pieds ($1500) and wait for two or three years until the female is up to size and start your breeding. Sure you can breed the het male sooner - but realy if you are going to go the possible het way - you might as well buy a pastel.
As for Granites - we saw lots of killer granite morphs recently - the ebony (of course) granite mojos, granite albinos, etc. - they just make cooler looking animals - worth the extra $300 depends on what you are breeding it to. Take a look at the hunters guide for more on True Granites.
