John,
My personal experiencing in using HDbaseT products as a custom integrator is that they work as promised. Though I would recommend either big name brands in the industry or purchasing through an integrator for selecting the right models. Also be sure your terminations are rock solid on your Cat 5e/6. My personal favorite product to use now has 1080P, RS-232 and bi-directional IR along with POC(power over cable) so that you only need to have one end powered. Great for minimizing connections and space behind a display. Would be glad to discuss models used and assist in selection but as I have found many times here, if I recommend or am enthusiastic about a brand in a post the trolls come out.
