Gthrush: I realize that your post is seeking input on a 78-rpm cartridge that is better than the Grado, but I thought I'd respond with info that may be helpful to others who also want something for 78-rpm playback. For those on a more restricted budget, don't overlook Shure's cartridge line. They have a cartridge/stylus made specifically for 78-rpm records -- I had one some years ago, and it worked very well.
In addition to checking with Jerry Raskin's Needle Doctor, also contact Garage-a-Records (prices are sometimes better than Needle Doctor). Here is the link to Garage-a-Records:

Good listening to you!
