Rubber for much older players used to pre-built paddles?

This question is not for myself, as I'm a younger player (30s), but for these older individuals (late 60s to mid 80s) I play doubles with once a week:

The older players I play with spend lots of money buying new pre-assembled paddles - the kind with cheap rubber sheets semi-permanently attached to a low quality blade. Many of them are falling apart, and clearly messing with their ability to play consistent shots. Since I make blades and have a surplus of 5 ply blades, I would like to start giving them as gifts to my much older friends, but I cannot afford to buy rubbers for them (they need to buy them and I'll glue them for them). It also wouldn't make too much sense for them to have high spin, high speed, or tensor rubbers. Some of the players have ok form, but many play junk balls (i.e., high, always/only sidespin, goofy strokes) they have "practiced" for the last 50 years. Some are open to getting better and are starting to develop modern strokes.

With that in mind, do you have any suggestions for decent, durable rubber for beginner to low-intermediate players that are ideally under $25 a sheet? I say $25, as some players are better than others and some like spending more money than others...but sheets in the $10-15 range would be ideal.

Palio AK47 Blue? Gambler aces? 729-5?

Thanks!
