If you like Super Pastel combo's then why are you picking up a 1.0 Spider? It doesn't fit into your plans. A 1.0 Pastel ($50) would fit into you plans, as would a 1.0 Bumblebee ($400-ish).

A 1.0 Bumblebee would fit into a 0.1 Pastel nicely and get you some Super Pastel morphs. You could get into that project for under $500 if you shopped around a bit.

Something else to think about
