I was at the Expo in WA just a few weeks ago and a lot of the booths were selling the Machingers so I don't think they have been discontinued. I bought a pair and I really like them. I like having the grip area just on the fingertips.
I had a pair of Quilter's Gloves by Nancy Odom. They have the gripper dots on the palm area as well as the fingers. I had to cut the tips of the fingers off because they made my hands sweat.
Quite frankly, I think garden gloves would work well too.
