The Rugers are good pistols, I won't dispute that, but I find them heavy and clunky for my tastes. Just my opinion.
I prefer a good handling auto pistol that points naturally and which is also reasonably light. So, if after handling the Ruger, you are looking for something a bit sleeker, lighter and better handling.......
The Colt Woodsman is my hands-down favorite .22 auto of all time, but you won't likely get one for under $300.
But you can get a Hi Standard Model B, which is very close to the early Woodsmen in terms of feel and ergonomics for $200-250 or so. For that matter, a number of the Hi-Standard autos will be found in your price range. I have never shot any Hi Standard that wasn't pretty accurate.
Google Guns of America or one of the auction sites to get an idea.
If you insist on something new, I also recommend the Buckmarks.
