Sram and Shimano offer 12-32t in 8-speed, with only a 18-21t jump where the 3-tooth progression starts.
Odd, I found just the opposite - Sunrace was the only one I could find in a 12-32 and only Shimano had 11-32.
Anyway, if it were me, I would be throwing on the 12-32 for exactly the above reasons and going with a 48t chainring in front. But no matter what you do, if you don't like it and decide to change, you weren't wrong, you just took a step down the path toward greater happiness.
