Thought I'd make a quick post about our annual this year. Came in just over
$1k, for the normal inspection, plus:

New EGT probe (EGT was inop)
New Brackett air filter housing. (Due to AD?)
ELT Battery
Gaskets... #1, #2, & #3 valve covers, dipstick tube, both mags, and pushrod
tubes on #1.
New Voltage Regulator. (we had intermittant charging problems)
'Installed' autogas STC, filed paperwork, etc.

About 16.5 hours of labor all together. Another lucky year!
