It depends on your needs. I remember the band days, we were poor and the guitarists would occasionally need to share an amp. They hated that. Each person likes their own set up & tweakage. Sound quality was just not good.

I say go for it. If a small amp is what fits your needs, then that is what you need. If it helps, I have a 20 watt Peavey, but went out and bought a 5 watt Vibro Champ (which I love!). But I am currently considering another 15 watt to get the Super Champ just because it has channel switching. I really don't need the extra wattage, though.

But I also find myself asking the same question and wondering if I should go bigger anyway. But if I did, it would be useless because I'd never use that volume.

...I bet this is not helping at all :rolleyes:

IMO, you need a second amp. And if a small amp is all you need, that's what you should probably get. I have heard great things about the Spiders. :)
