This site shows it for $135. I've never shopped there, just the first link that popped up on google for me.
With the
turbo head button (~$20) and the
RE11 pipe (~$55) the motor has a very strong mid and top end charge. Bottom end is very smooth and you wont be lacking any power. Mine was as fast as anything down the straight but did leave me looking for a smidge more grunt on the bottom. I dont think you can touch it for ~$200 (pipe included).
