When it comes to cabinet hardware I am the kind of guy that likes to pay a builder to do the work as my DIY skills are sadly lacking. If however you are the type of person that has a few home handyman skills you can save a lot of money by getting your bits and pieces from a site like knobsandhardware.com and doing it yourself.
The thing I like best about their website is the fact that you can not only shop by type of accessories, you can also search by brand, which makes it a lot easier if you are trying to replace something with the same thing again.
