Reggae, Rockabilly and Gospel, not in the PA much of the time, sometimes by choice.
Just ask @BurningSkies about PAs and reggae rigs.
My mind doesn't work in these kind of wattage terms when it comes to reggae bass, but then I don't think it really does with other kinds of music too. What I get here is that you're looking for something that could be a reasonable survivable gigging rig that's compact and/or loud enough for stage work.
It seems that with what I'd consider a conservative cash situation, I'd be looking at finding a decent quality 112 like a Aguilar GS112 or something like a Genz Uber 210, modern and well designed will cover a fair amount of tonal ground effectively and stay clean. You should be able to get in used on one of these (in fact, you'll have to, since they're both out of production), but if you're looking at under $1k expenditure, I'd be only considering used anyway to maximize your gear to your spend.
Heads? I'd be looking at 500-800w heads that are good condition used. I'd look at the Genz range (Streamliners, Shuttles), Aguilar TH500, Markbass LittleMark800. If you can stretch, a Mesa Subway series would do you well.
This strategy would still keep you compact & fairly light and tote-able, so similar to living in the combo world, but with better end result.
If you're looking to provide some FOH support for bass in more than 'corner of the bar/small room' type gigs, I honestly think you'd need to stretch your budgie a good chunk to be effective. You'd be looking at one or two modern 'super-cabs' and a power sitch that's more like 1000-2000w.
