Belt is $35-$40 usually, and you can easily replace it yourself, all that is needed is a 17MM socket & wrench, or pull bar.
There is a 'boss' cast into the tensioner pulley, ( the pulley located at 2 o'clock from the crankshaft pulley when viewed from the front )
The 'boss' is at about 7 o'clock below the pulley.
Put the socket on the boss and rotate the tensioner counterclockwise after you have threaded the belt, put the belt over the tensioner pulley and release pressure. ALL DONE !

NOTE: often the belt has come off due to an oil leak in the area of the oil filter - CHECK THIS !
or you will be putting on yet another belt.
