I hate Plumbing, appliance work and electrical work. However when possible I do it myself. No matter what 1/2 hour is exceedingly good, it is a perfect situation, almost a clean installation were everything is perfect, assuming you have the proper tools, no issues with the old hardware coming apart, nothing breaks, nothing has to be cut or re-routed, and no additional trips to the store for tools or parts. An hour and a half very good! Pat yourself on the back, you are part of the I just saved $100 to $200 crowd. Home appliance repairs can be a nightmare too, but well worth DIY. I have saved $100's if $1,000's fixing appliances on my own. A $50 part can cost you $300 to have a guy come out and fix it, and they will sell you the $50 part for $175. It may take you a day or two, a "professional" two weeks and waiting around for your scheduled time. Kudos to you.
