You can get longer HDMI cables that have larger gauge conductors and special compensation circuitry built into the cable, but they cost a fortune. Just recently I did a bunch of plasmas in a restaurant using HDMI baluns and 75' CAT6 cable from Monoprice. The baluns were about $18 a pair (part# 8121) and the CAT 6 was about $10 each. (two CAT6 per link) Total cost for each TV was less than $38, since you get a discount for multiple quantities. I thoroughly tested the performance with 1080p Blu-rays, so they shouldn't have any issues with 1080i from the cable boxes.

My 35', 24AWG HDMI cable was <$30. And there are amplifier/equalizers for HDMI. There are HDMI/CAT5e and CAT6 baluns all over the place. Just make sure you get the right balun for the cable you use. Monoprice is an excellent candy store!
