MED is quite a good tool to import and to convert models, and to check converted models. It improved over the time although some parts got more complicating that they had to.

I used it for a long time for modeling and animating as well, but there are better and faster tools for that. I started to learn blender in the last year, and use it now exclusively.

Devon, if you want to make further progress with your modeling skills, I recommend you to learn blender as well.
