Stillpoint Component Stand

Has anyone tried one or two? They seem to be getting some positive press but are hellishly expensive. Thanks.
thanks duane. have you tried the component stand between speakers and a carpeted floor? wondering whether a carpet could cause some problems.
I havn't but the have inverted risers for carpet that Intuative design, (a speaker manufacturer that uses Still Points) says works well. If you call them they are rather helpfull.
