David Eden stuff is waaaaaaay far from crap and from cheap too, the guy put in new speakers, would be a good idea to hear which model he used coz most well built cabs (like Eden D series stuff) work wonderfully with their custom speakers (I think now they use eminence ones for newer models?), but results may vary with replacements.
Not that it's the most important point, assuming you have to play punk stuff, because eden and SWR with original speakers tend to sound quite "hi-fi" to an extent.
Same goes for SWR (the nice ones like that son of bertha, at least) are not "cheap cabs". That's a 15" speaker, you may want to go for 10" to have faster-better attack/highs without necessarily having to use a tweeter..
The Marshall stuff weighs a lot to be carried around at shows (like 50kgs), and it usually sells for way less it's actually worth (meaning: prices are low, quality is mostly good, weight can be a pain in the ass). I heard low prices are coz people won't consider Marshall a "brand for bass stuff", but if you like the sound their cabs/amps are not bad at all.
Peavy usually has good volumes, and are cheap but still decent enough if actual "sound fidelity" isn't an issue.
To answer your question better, there are some more questions to be made:
how "loud" is the rest of the band? Is it drums+guitar+you(bass?)?
what instrument will you play through your rig?
Ever reharsed with those other guys yet?
