What should I get at the expo?

I'd pass on the albino mojave male.
I'd get a visual OG male for your female, maybe Pastel Orange Ghost...personally I love mojave and cinnamon og's, but thats just me.
and...you could breed him (cinnamon og) to your pewter bp female and possibly get super cinnies!

its just a fact of life that some people have more money than others, jealousy gets you nowere.

one of my friends just got his first airplane; a few years earlier he spent 5000 for a realistic multi-screen flight simulator cockpit. and i still need to save up a bit to get seriously started with BPs. im not jealous and dont "female dog" about it and maybe one day he will fly me around over the mediterranean coastlines. two of my friends are on the verge of becoming millionaires, they dont look down on me and im not jealous, and so it doesnt affect the friendship at all.

and when another breeder in my town has the money to get some genetically really awesome BPs for hobby breeding, im all for it because when he produces hatchlings in a few years, i have a shot at getting some really nice stuff cheaply.

Being jealous just creates barriers and gets you absolutely nowhere. There is too much random chance involved in life choices; arrogance, jealousy, or self-pity just dont make sense when you understand this.
