The only reason to spend more than a few dollars on an HDMI cable is if it is capable of being bent near the connector, which is not good anyways, but some of the better cables will hold together better at the ends. 1.4 vs 1.3 is not that big of a difference, get the 1.4 if it is the same price. You can pass ethernet over 1.4 as well as higher resolution. Most likely your devices don't support either of those anyways, so it doesn't really matter. In other words, don't worry, get the cheapest possible one you can (that is at least 1.3, you probably can't find the older ones anyways though). I actually am in that first situation where the HDMI gets moved, and kind of bent, and taken in and out a lot. I just had my first cable break the other day, after a few years of that.
