I use the ThimbleLady stainless steel thimble and love it. I migrated from using the top of my finger to the pad and do find it much more comfortable. The s/s thimble is about $30. They have them in sterling silver as well but even though I did wear a hole in the original one I bought I decided to continue with the stainless as it is a stronger metal than sterling. If you go to their website they explain how to measure for the correct size for you. I use my middle finger for pushing and use the M/L size and it works very well.
