  $( "#amount" ).val( "$" + $( "#slider-range" ).slider( "values", 0 ) +
            " to $" + $( "#slider-range" ).slider( "values", 1 ) );

to

  $("#amount").val("$" + $("#slider-range").slider("values", 0).toString().replace(/(\d)(?=(\d\d\d)+(?!\d))/g, "$1,") +
            " to $" + $("#slider-range").slider("values", 1).toString().replace(/(\d)(?=(\d\d\d)+(?!\d))/g, "$1,"));

and

$("#amount").val("$" + ui.values[ 0 ] + " to $" + ui.values[ 1 ] );

to:

$("#amount").val("$" + ui.values[0].toString().replace(/(\d)(?=(\d\d\d)+(?!\d))/g, "$1,") + " to $" + ui.values[1].toString().replace(/(\d)(?=(\d\d\d)+(?!\d))/g, "$1,"));
