In case you're on a search for true quality door hardware, then this St Gaudens solid bronze entry door handle set from Home Depot would be spot on. This St Gaudens door hardware is made very well, and the solid bronze construction says quite a bit right there. Apart from top materials being used, these door hardware products also feature a very nice and timeless design which is decorative without being over the top.
The price of this set below is $100 which is pretty high, but not outrageously high by any mean. If you're serious about wanting quality products which won't give in after a couple of years of use, and that also look very nice, then you simply can't go wrong with this set.
Of course if you had a different type of look in mind, then paying a visit to one of the home improvement stores (Home Depot, Lowes or Sears for example) could be a good idea since they carry a lot of different brands and products in various designs, materials and price ranges.
