Sorry for the delay...
Brands: I have a prference toward higher end gear... Not going to lie. Bows, guns, bikes etc. I have champagne taste with an "improving" wallet

. I don't kind spending money on gear as its my hobbies which drive me. Some like gambling, some like strip clubs or golf... I buy outdoor gear. Anyway, I digress.
Kona bike store in Bham has a great selection of 29'er HT mtn bikes with front suspension.
Novara(o?) at REI isn't so bad... Your drive train is key. Don't go low-end.
Canondale always makes great products... Hard to argue against their frames.
Specialized... Paying a lot for the name.
Scott... Don't know much personally.
Bikes are like rifles... Some one KIMBER, some love Ruger, others, Winchester. Ride a few. Buy one and love it.
