The hardest part of having a small hobbyist collection is going to be keeping it small. Really think about the direction you want to go and try to stick to it, which is going to be much more easily said than done. Personally I think I would go for a visible pied male since it takes the guesswork out of the equation down a generation or two. Gambling a whole breeding season on a male hopefully having the proper genes or throwing 3 years at a female hoping she has the right genetics isn't the path I would choose. You won't get those visible lavs your first generation, but that's the price you pay I suppose.
This is going to be your breeding project, though, and ultimately your decision. You want fire? Get a fire. Pastel? Go for it. There is no right or wrong answer for what to purchase or produce.
