It depends on your riding goals...If you plan on riding thorough a lot of very hilly terrain, rain, snow, slush and grit, wet gravel roads, then disk brakes will save your rims from wearing out. If your riding is mostly on clean roads in nice weather with maybe an occasional rain, then get rim brakes... I do like BB7s because of simplicity and most bike shops stock pads for them...Getting brake pads for hydraulic brakes can be a problem because there are just too many different models out there and most bike shops don't stock every type of disc brake pad on the market. Sometimes you have to order online of through your LBS....Pads for rim brakes are available everywhere and a lot cheaper then disk brake pads...So my vote is for rim brakes or BB7s and I would avoid hydraulic brakes.
