Not sure if you guys have seen this but here is a controlled HDMI cable test with many lengths and manufacturers tested. Make sure to check out page 3 of the article where it has all of the test results. Also some good articles referenced at the bottom of the first page on HDMI in general. Bottom line is 35' at the highest data rates isn't going to happen with any cable by itself. At lesser data rates it might not be a problem.

As mentioned above, monoprice does very well on the cheap while some high $$$ cables boutique cables fall flat on their faces.
