Any opinions on this particular brake replacement set? Link

From the description it's a full set of front/rear calipers, brake levers and cables which would go onto my winter bike (Mongoose S20 MTB). The key concept is they're cheap and for about $64.15 shipped I can get an entire set of new braking equipment. This will save some time rummaging around in the parts bin at the LBS where things can be a bit hit or miss as well.

I think the set contains some type of Quartz brake levers with MT 14 brake arms from other site descriptions..

I should mention the bike is completely set up as a winter/foul weather commuter, no off-roading really.
