What accessories are you looking for? You might try contacting Loggy Bayou. I heard they are the company who bought Loc On out. Supposedly they were going to continue to make 4 Loc On models but the last time I checked, their website had not been updated since 2001.
I just bought two Loc On brand stands off ebay a couple of weeks ago. Both stands were new and in the box and the price was very reasonable. It was an archery company some where up north and they auctioned several Loc On stands.
