Re:
The stuff I like now, both retro and modern is influenced by what I had in the 90's, I restored a muddy fox courier comp because mine was stolen in 91, I built a proflex because I'd had one in 92 although the one I built was a 95/96, also had an explosif in 94 although it was a 92 model frame (was hung in the shop unsold for 18 months) obviously I have a lot of oranges, I bought my first in 96, a p7 nickel xt/xtr, it was awesome and I loved it. After this I got in the trade at a GT dealer so I rode them and liked them, then I worked at a giant dealer, I rode giant, meh . . . OK I suppose, then to an orange dealer at which point not only did I ride their bikes I also got to know the people at orange and that makes a difference for me.
So my brands of choice are orange, GT, muddy fox, kona, proflex.
But I am a bit snobbish about stuff now, for example I don't like konas now (generally) but specifically I wouldn't buy anything after the change from second level imports because that's the point they went in to halfords, same with GT, I wouldn't buy anything from the point they went into halfords but also the more recent ones I think suck mainly because of the over use of "zaskar", rather than it being a model name it is now a range, several models with various numbers added to take advantage of the name that people knew as the then top model.
That said the brands above are mainstream brands I have always liked the smaller individual brands/builders.
