Well, I did think solicit possible advice on moving on up. However, looking at ebay, the cheapest FR-7fz is $1500. The problem for me is that I don't know how to find a "perfectly working" Fr-7fz. I'm a photographer and believe me, every piece of photo equipment on ebay is "mint" or "near mint" even when you can see scratches, dings and paint worn off. So, I take it with a grain of salt when people say whatever they say to make the sale. My concern is that for me, that's a lot of money and that I end up with a cartridge that needs repair.
In the current state of the world today, it makes more sense for me to send it in to Soundsmith. So, I pay out $500 to fix it up. The cartridge is a known quantity to me and I'm back in business. Then, looking down the road, I can start thinking about upgrading. In this case case I've gotten a tip from chakster that the "fz" is better than the "f" so I don't waste my time with an incremental upgrade.
Thanks everyone! I'll report back after I get the cartridge back. I'm hoping to get it out tomorrow.
