The Morrel-Thule server was an abandoned project that the creator left up where everyone gets GM access. You can create a character there, make it any level (up to 255) and give it any gear you want. From there you could try out each class.

It's a fun server to play around on for a bit. You can ".cast" spells so even as a non-solo class you can heal yourself and buff yourself for a close to accurate experience. But I mean without being in a group at the appropriate level with the appropriate gear you're not going to get a true feel for the class.
