I have the same setup Z32+ power fc in my car tuned by boys at asg

second hand power fcs come up quite often check rexnet as well can be had much cheaper than new

if your not keen on second hand,I used nengun once and they were very good, I hadnt heard much about them but they do guarentee delivery of the part, the part I bought from them was much cheaper though so I wasnt too fussed about risking it


z32s from memory can also be picked up from from coventrys for 300 if your not keen on ebay
