I picked up a pair of used Zeothecus amp stands used, but near mint condition.
These things are strong enough to hold a couple hundred pounds without the slightest groan. Before that I had a pair of Targets (think they were anyway), and they were not up to the 75lb of weight.
I really liked the racks that were on the link you supplied, and may invest in a LP rack. My current speakers are of lace wood as well, but think I'd rather had them in walnut. Also looks like I'd have to have two units as I have close to a thousand LP's right now, and I'm in the market for some good book cases. May just drop this one on my Amish friends over by Milroy.
