Perry,
You should reconsider, the Sig Kadet Senior is a very good trainer, for a overly stable "floater" with sluggish penetration on landings in any kind of wind.
On the other hand is the World Mach 1 trainer, it has a bolt on "semi symmetrical wing" with a bolt-on self aligning tail assembly. It's a very tame trainer when set on low rates but comes alive on high rates so you can have fun with it as your skills progress and is capable of decent aerobatics which I teach my students early in their training just so they know what it takes to move the plane around and what the plane is capable of.
I always have a trainer in my hangar, I like to throw it around and do things with it I'm afraid to do with my $2000.00 Mustang.

P.S. The Saito is a great choice, maybe the new .82? And don't be afraid of a little more power on a trainer, you can always throttle back...
