How about a used ZW-C ? You'll get the 4 variable outputs but 1/2 the cost of a ZW-L. I have the version with 2 180W bricks - these go for $250-$300. Then you can run 2 trains, and possible expansion if you want a third (upper level, trolley line, etc). I'm no electronics expert, but this was good enough for me. I didn't want to spend the $$ on a ZW-L.
