After a lot of deliberation I decided to replace the TBO engine in my 150, and the option I chose might be of interest to other folks in the same boat.

Continental Motors Services offers a "kit engine build" where they build an engine with 100% new parts, then transfer the data plate from your old engine to the new one. The only difference between this and a fully new engine (except price) is that your log shows the total engine time of the old engine -- that is, that the old engine was "overhauled". The price for an O-200-A was $22,398 vs. $27,104 for a new engine or $24,161 for a factory remanufactured engine. The kit build and remanufactured prices are exchange for your old engine; I'm not sure about the new engine price. The kit build price includes a new alternator, magnetos, spin on oil filter, and plugs, but I don't believe mufflers are included.

I assume that having the kit build engine might reduce the resale value of your plane compared to an officially zero time engine, but that's no matter to me since I'm not planning on selling. So I chose the kit build as a less expensive way to get a totally new engine. The old engine is out and on its way to the factory, and I expect the new one in about 3 weeks.

I'll be glad to share my reasons for replacing the engine rather than overhauling it, running it beyond TBO, or buying a different airplane, either via PM or posting if anyone is interested. It certainly isn't the best option for a lot of people but it was for me.
