I'm over brands, now that I think about it. The only brand I will buy is Hermes, but otherwise I prefer any nice, functional bag that I fancy, don't care if it costs $40 or less as long as I think it'll have a purpose in my "collection", whether it's the colour or style. I'm actually eyeing couple of pretty ones at a shop down the road, they might be *gasp* "inspired", but I really have no idea as I don't know any styles and models all the desingers are making.
I have a lot of bags but one of all time favs is my LV mono speedy 25. While there are a lot of peeps out there carrying fakes, I still use mine knowing its real. Don't let the haters bother you, use your mono bags.
Burberry (I bought the Heathcliff Satchel yesterday and returning it)
Chanel (I love them on others but I'd be afraid that it would rip)
Any celebrity designed (endorsed) bags
