I tend to see B18B's around the same price as B16A's. If you are talking about first gen B16A's, you should include B18A's in the run. A 92-93 B18A is easier to set up then an 88-91 B16A, but not by much.

If you are interested in simplicity, you need a 92-95 SiR-II B16A. They cost over $2k for the swap. More expensive then any B18B swap I've ever seen.
