I agree with everything WWW said about the Tomahawk. O K, some of its characteristics are a bit unforgiving but with constant attention to detail (and isn't that what learning to fly is all about) it won't bite you and you'll end up a safe and skilled pilot.
I've seen the tail waggle in a spin but what the hell the thing was designed for it.
Save your money, go for the Tomahawk and convert when you get your PPL. I converted to the PA28 Cherokee, the C182, and had my IMC in a Warrior all within 25 hours of the PPL, thanks to the tomahawk.(and my instructors of course).
If you can land a PA38 you can land anything.
Cheers
