One thing I noted in your list of estimates: The IMS Upgrade is not the same thing as the IMS Retrofit. It would cost more and require engine removal and disassembly for the upgrade to be done, and the cost would be more as a result. The IMS retrofit goes for about $1600 out the door at the local shop here that is certified by LN Engr. ~$620 for the IMS bearing and an RMS and the rest is labor @ $98/hr. Just something for you to use to update your info there.
I hope you also don't mind if I PM you with grammatical/spelling corrections and such. It's one of those things that always bugs me when I see a professional-looking site with typos and such. No offense meant by it.
Very interesting site so far, and the effort to consolidate information is definitely appreciated.
