I checked those engine prices at their website. Wow! Just like you said. They’ve really went up in the last few years, unless they have a pretty significant markup on them. Time to get out trade-a-plane out and do some checking... ;)
You can get the 100hp engine (uncertified) for about $6,000 less at $18,578.00 here:

And they said there's NO inflation....
