My story is basically the same as MelG. Can't justify the cost of a tower so built a reflectorless M4 for about $20 and spent an extra $20 for chimney mounting hardware. I tried a couple of commercial antennas since then but they couldn't beat the M4 for my location. The other costs were tuners for HTPC. Tried a couple of Hauphauge cards but settled on a HDHomerun dual. Added a preamp but it doesn't make much difference with the HDHomerun. The final tally of components actually in use is about $220. The total for all things tried, whether in use or not, is about $550.
