is it worth doing engine swap from m40 to m20?

Yea....i was gonna say I said M40b18....but the point is I was wondering and getting ideas from you guys who have done it because ill admit it I dont know that much about the swap. And for the s62, i wish but its way off my budget !!! In Australia its hard to find a clean e30 let alone a 325i so i settled with the 318i....i couldnt resist the e30 its such a beautiful car :D, in America how much is the engine m20b25, including the wiring harness and ecu ??? (i know it depends on the condition, but just a rough price please)
thanks
