Ok when I look on Ebay for gear I don't know all the good brands of camping equipment, so could you guys add to my list for quality brands.
Here's the brands that I think are good, from reviews I've read.

Tents: Marmot, Big Agnes, Nemo, MSR, Mountain Hardware. Do Kelty make quality tents also?

Sleeping bags: Marmot, Big Agnes, Mountain Hardware, Kelty

Packs: Deuter, Osprey, Gregory, Kelty

I don't know what brands are good for smaller items, but I try to go buy reviews I can find.
And With those brands, Do they all make all sorts of quality camping gear or are they better at making one item more than others?
As in lets say Marmot made real quality tents, but their sleeping bags are to be avoided. Or something like that.
Or any tent, sleeping bag, packs from any of those companies would be a quality item?

Thank you again
