MS Mouse Replacement

I have a Microsoft Natural Wireless Laser Mouse 6000

that is getting a bit iffy at times. It's a beast of a mouse, but I love it-
the way it fits my hand, the easily accessible buttons, etc. I've tried a
few different mice, looking for a decent replacement for it, but have found
nothing that comes close to it for me. Here are a few I've tried:\

Logitech Wireless Performance Mouse MX (This was the closest, but quit
working less than 3 months after I bought it. Logitech was no help in
fixing/replacing it):
https://www.amazon.com/gp/product/B002HWRJBM/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

Anker Ergonomic USB 2.4G Wireless Vertical Mouse (close, but too vertical):
https://www.amazon.com/gp/product/B018LR04B8/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

Logitech M510 Wireless Large Mouse (not really a "large" mouse, or at least
large enough for me):
https://www.amazon.com/gp/product/B003NR57BY/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

Anker® Full-Size Ergonomic Wireless Mouse (very close, but quite large
enough. This is the one I will probably stick with if I can't anything else
closer to the MS):
https://www.amazon.com/gp/product/B00B0TXEEY/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

My hands aren't all THAT big that everything should feel so small (I wear a
medium glove). I guess it's just the bulk of the 6000 that makes the rest
feel puny. And I did give most of them at least a month of use before going
back to the 6000, so it wasn't just a 10-minute "This mouse sucks" decision.

If anyone has a suggestion for a similar mouse that isn't exorbitantly
priced (I'd like to stay well under US$50 if possible), I would like to hear
your experiences with one.

TIA!!
