I don't like the buyoff at all at lower levels - the LA+1 races can dominte the other PCs if they get their buyoff too early. I'm all for the system, though, as long as the buyoff is done at a level where it doesn't become significant anymore. So, for example, LA+1 characters could only buy off once they'd reached level 6, or LA +2 creatures could only buy off once they reached level 12. Or something like that. It meant that at lower levels the LA would hurt but not so much at higher levels. At lower levels those abilities can be really helpful.
