Oh man I dont wanna send mine off. 149 nicker + post is a bit steep with the shitty exchange rates anyway. Guess i'm still looking.

when PSD used to sell them they were £150 exchange so that is still a decent price.  Maybe try g-werks and jabbasport.  They aren't simple to make though as the throttle plate has a weird opposing chamfer on it and needs a lot of manual adjusting to get it to seal right.
