One option if you play at low to moderate levels is a used Roland Bass 20XL Cube. I also have the Rumble 100 V3 and it's a very nice amp with a warm sound, but it may be overkill depending on your sound levels.
The Roland is smaller, lighter but also much lower powered, but I can use it for gigs with low volume or when I accompany acoustic instruments. It also has a number of amp emulation sounds and a built-in tuner, all of which is very handy.

OTOH, if you want some reserve power, the Rumble series would get a strong vote from me. I like the sound a lot and it's light and easily portable. The series comes in amps with wattage at 15-25-40-100 and up.
