nearly all mountain bikes these days have hydraulic brakes on them now. Here is one: http://www.performancebike.com/bikes/Product_10052_10551_1074301_-1_20000__21002 in the high range and here is one in the low range: http://www.performancebike.com/bikes/Product_10052_10551_1061231_-1_20005_20000_20500 and nearly all bikes in this price range are so equipped and most in the sub $300 range wont have them but some will.
