I love the blu motion and that is fairly expensive itself!
I would have to look up old invoices as my General usually provided the stuff and I would just look in amazement at the prices, I do not think he really shopped for sales to much. We also used blu motion type stuff for the cabinet doors , but it was not blu motion just something similar. I think it was from Sweden, but I am not sure. I'll look it up.
You could take a door just like the drawers and try to slam them as hard as you could and then about an inch from the frames the doors would stop and slowly snap shut, pretty cool! They also held my kids body weight with the door open and him hanging on them, he is about 50 lbs so I thought that was pretty cool. All my stuff in this house can not handle that at all.
