Dealing with the same thing myself. LOVE my old glossy black SCS large, super mild wear for the amount of work it's done.
This whole new stainless steel is healthier era has me wanting to upgrade and pull the trigger, but one part of my brain says it (the mildly worn edges) can't be killing me from the amounts I've seen worn off. It might be, but I can't justify the price honestly.
Can't lie though I love my large SCS, I've used a few others and hated them honestly. I can't use something I hate using regardless of potential health stuff which hasn't really ever even been proven, so who knows honestly what to believe.
The only super mild wear I can see is from the teeth around the magnets on the top and bottom. No idea how to post pics or I would...
My stoner math shows the grinder is 5 years old, 2 oz a month = 1.5lbs a year x 5= 7.5 lbs total it's chewed through.
If Santa Cruz ever made a SS copy of their large in 3 pc I'd buy in a second even if it was hundreds of dollars simply because I love the function, design and most importantly the shred/cut.
The grinder is a totally personal thing in the end though, you've gotta literally handle it daily so it has to be comfortable in your hand, myself I can't even look at anything below 2.5in also.
