Numrich GunCorps has Diana 350 magnums in .177 cal. for $249.00. I think mine was 269.00 shipped. It has the new t06 trigger.
I was told not to get a magnum springer for my first coil spring gun as they would be too hyper to shoot well.
I’ve had no trouble keeping 3 to 5 shot groups from the bench in the .2 to .3” range at 20 to 25 yds.
However, the first 50 shots would give 1/2” vertical strings out of the box... after that it settled right in... or I did lol.
I put a BKL 6 screw droop compensating baseon it, locktite on the screws and it’s still holding zero after a few 1000 shots.
