R. Chahoua vs. R. Sarasinorum

I am having trouble deciding what I want to buy next, so I need your help (and reasons why also) to figure out whats best.

What I keep now:
Crested geckos (all shapes, sizes, and many morphs)
PI Chahoua (proven pair - female just laid her 1st clutch of eggs on 08/04/12)
High end Leo (pair) (these are for sale so won't be part of collection)

What I could get (this is where you come in):
Sarasinorum (normal chocolate phase pair) $200-$300
Sarasinorum ("blonde"/yellow phase pair) $300-$450
Sarasinorum "white collar (pair) (expensive both to buy AND sell) $1,200 +/-
PI Chahoua female (add to my PI pair) $900 +/-
Mainland Chahoua (pair) $1,100 +/-

Let me hear your oppinion, and I added prices to have you keep in mind that they will SELL for close to these prices, and so please do not tell me to get something that I will be overwhelmed with because they are too expensive for people to buy. I do this for the love, but once you get so many, there is a point where I will have to sell. 9EXAMPLE: if I sold the White collar for $500-$600 each as adults, would people BUY something like that, rather than a "blonde" phase thats much cheaper?). Please let me know your input! Thank you all.
