Jimmy,
If you decide to get some stick time with a proper second plane, I recommend the World Models T-34 Mentor

It was my second plane and I enjoyed it as hell (using a Super Tigre G51). It will take the engine and gear you have in your Eagle (assuming you had a 40 to 51 size engine) so you only will be spending on the $130 airframe.
Also, you could get a low-wing taildragger to get used to taildraggers, a Tiger 2 comes to mind, it's a little more expensive though. And if you're on a budget you could get a Sky Rider MKII for $70, it's uglier than a kick in the face but it flys very good and you won't cry if/when you crash it
If you decide to follow this path, you can (suppervised by your instructor) gradually add some weight (at the center of gravity of the plane) to get the feeling of how warbirds usually fly & land.
