Was just checking Ningyoushi and noticed that they have the L-Slot and the Proto-Fett for sale:
Anyone still looking for these might want to check these out.
Thanks for that! I picked up the basic set and those two chases (and the Watchmen kubricks on sale). I really wanted the L-Slot over the J-slot, so unless I can find a really great J-slot deal, I think I'm set!
