HookedOnSound,
I don't recall how much it cost. I bought all material at Lowes (or Home Depot, can't recall which). I ended up with only about 1 foot of unused racetrack. I used Wiremold's CordMate, plus the related elbows, interconnects, etc. If one were to go to Lowes and see how much about 60' total of the "Cord Channel" cost (they sell it in 3 or 4 foot sections, or thereabouts), plus a few bucks for the elbows, etc., one could deduce about how much I spent. It was user-friendly to install for someone like me, who is the complete opposite of Bob Vila.
I can see how installing a product more securely with screws and in place of a baseboard would be more secure and eye-appealing. However, for its ultra-simplicity, and if it has enough space for the wire you need to hide, the Wiremold products work well. Again, I've had zero issues with the adhesive coming loose. When I installed it, I pushed very hard and HELD it in place for a few seconds to ensure a good attachment.
