I use the Mayday premium ones. I haven't had them long, but they seem fine, other than a small percentage being too tight to use.
I don't think they fit your other criteria. They are thick and won't fit in the original slots. They are a bit pricey at ~$2.50/100. I think their cheaper sleeves do fit in the original slots, and are about half the price, but have also seen negative comments recently about Mayday, so I don't know about those.
