That one for 17.5K ain't bad for starters. I am looking forward to the next "market update report" in Excellence magazine by Bruce Anderson on the latest longhood estimates. I believe the longhood market update comes out in one of the spring issues.
Good 1973.5T's are out there at reasonable prices but it takes time to find them. Stick with it and you'll find the right one for you. Just make sure you get a mechanic who can do an excellent PPI. The thrill of the hunt is half the battle. To pay 55K for a 73.5T is outrageous!
