I would look for an Olt 66, a real classic. I've had mine since the 70s and if I could only take one call with me, that would be it. Easy to blow, easy feeding chuckle. Pristine Olt 66 calls have become something of a collectors item, but you can still find well used ones for around $25 - $30. An outfit called DJ Illinois River Valley Calls has also brought them back into production.
