Even the lowest white pieds are going for about $700 and up depending on age and sex. If that's all you have to invest, I suggest starting with a normal. The proper set up will cost that much alone with thermometer to control the heat, thermostat, hygrometer, heat, 2 hides, bowl, etc..
They are not a very forgiving species. If everything is not perfect, they get respiratory infections easily which then costs hundreds at the vet to save it's life. Not to mention other problems that can occur.
Hang out here for awhile. Read all you can about husbandry. Check out the care sheet. The one posted on bpnet is the most accurate one I've seen. Get to know as much as you can before getting one. Research and price the supplies you need and have the proper size enclosure all set up and ready to go before getting a BP.
The people here are friendly and helpful and many many members also breed. Morphs will always cost more. It's an investment for the long haul with these guys so find out as much as you can. Most people start out with a normal so they can be sure they know everything they need to know before getting into morphs.
