Two quick thoughts: For indoors, try a Terk HDTVi (not the amplified version) and you will pick up all the channels in the green part of the table that are off to the southwest. For outdoors, an RCA ANT-751 should be fine for the same group of stations.
You
might have some luck with picking up the Buffalo stations. If you want to persue that, or in any case, really, check out the appropriate threads at
DigitalHome where they've been discussing this for some time. Introduce yourself as you did here and you'll get a lot of good advice.
