Feeding my cubimal addiction leads to duplicates. I have the following, prices fairly flexible:
-bureaucrat 8k
-cactus 5k
-deimaginator 12k
-dustbunny 10k
-juju 5k
-squid (2x) 5k, or if you buy both a total of 8k
also, a frog and a crab can be had for basically anything. I'm partial to gameshow tickets.
Everything above also available for equivalent trade, ask away!
