The Rumble 350 is, well, Mediocre. But the kids at church haven't broken it yet and it gets used a Lot.
Cant speak for the Carvin.
The Peavey is big and bulky and feels like its weight distribution is horribly off. Its got enough power/ features for most, but I wasn't impressed with the tone. Im sure it would be great for a small/mid sized back line, but I wouldn't want to move one ever.
When you get in to the price range of these new, your stepping in to a lot of options. GK has a micro head and a few combos with the same 200 watt head in it for the same price or less than the options you listed.
Your volume needs are another factor.
If i was looking for a similar rig to what you posted, Id ether get a new GK MB200 head or a used MarkBass head (or insert brand name here) and a used Eden 210 or some other cab with mid level or better drivers.
I've owned a lot of combos in my days. That's one road I wished I never went down. Every combo I've owned has been a big compromise, and if something ever goes wrong, your totally out.
