I just puchased a Price Pfister shower valve (model Treviso 808-5DK) from Lowes. After opening the box to check it out, I not sure I like the quality of it. The valve body is brass, but everything else is plastic. The piece that the handle attaches to is also plastic and it seems like it could break with a good whack from an elbow. The pipe fittings are also female threaded rather than sweat joints.

Does anyone have any experience with this or similar valves? I'd also welcome any suggestions for a good quality mostly brass valve. Thanks.
