With lots of experimentation, I've been able to get my technique down and can make a cup on par with the $3-4 ones that I used to buy (oops). This seems to let liquid through fast enough to not over-extract the beans, so long as you have everything else set up the way you want it. brewmethods[dot]com has a ton of videos illustrating various pour-over techniques.
Minus 1 star for maybe being too thin along the bottom (I managed to break off the bottom piece by accidentally whacking it against the table -- fixed it with epoxy later) and being a bit pricey. I like the design though so I guess that helps.
UPDATE: both "legs" have broken off by accident by now in my drying rack, but not all is lost! I built a little wood stand with roundish hole to hold the cone in place about 4-5 inches above my cup. The flavors are actually much more crips, clean, and pronounced now. I attribute this to the drip distance, which allows the coffee to aerate and cool a bit as it falls!
