4yanx, It's my understanding that Grado will produce ANY of their wood bodied MM cartridges in mono format upon request. From what I understand the pricing is the same as the stereo versions.
Also, the Denon DL-102 is a mono high output MC that is still available.
I believe there is also a Shure model still available. I don't know the model #, but from what I remember it was more for the wider groove 78rpm record usage. The Grado and Denon both use standard stylii configuration.
Of course the Lyra is available, but I think it far exceeds your budget.
Hope this helps, Ed.
