UtahTim,
There are lots of RFBR Shooters who have multiple custom rifles, but you can only shoot one at a time. Lots of guys enjoy building and testing new gear. Therefore, quality rifles do come up for sale.
Here is an Equipment List from the recent American Rimfire Association (ARA) Indoor Nationals. Most of the top RFBR Competitors attend this event.

You will see that the 2500X action from Holeshot/Jerry Stiller is well represented. Variations of the Turbo are also well represented. Shilen barrels are most popular and there is a large number of gunsmiths represented. Some will argue that the Gunsmith is the most important variable.
The “Factory” rifles that you see on the list (Anschutz, Remington 40X, Suhl) are usually highly tuned, unlikely to have the Factory barrel.
If you are a lefty and require a left bolt, right port; DiOrio (Turbo) is your only option.
The Trident that I bought here on Benchrest Central for $2,050, slightly outshoots the $4,050 2500X that I had built. Richard Gotham was the Gunsmith in both.
If you want to be competitive, I would sell the Annie for the $2,200 you suggest and begging searching for a quality used custom rifle. You might reach out to Slick Willy over on the Rimfire Accuracy Forum. He has a lot of Customs and is constantly buying and selling. Here is an example of a Winning rifle going up for sale:

If you are in Utah, I don’t see a Club there that is currently shooting ARA:

ARA is starting a new Factory Class this Season. Maybe you can leverage this development to encourage your local Club to start an ARA Shoot. Targets available here:
