You are more likey to find edge banding in a hardware store. The problem with that stuff is that it won't protect the edge's like t-moulding does. I know home cabs dont get as many knocks as a cab on location but t-moulding does help protect the cab as well as make it look more authentic looking.
I can imagine that edge banding showing any uneven part of the cabinet edge as it is so thin whereas t-moulding is a little more forgiving.
Im in the UK and have ordered from t-moulding.com a few times and shipping to europe is really fast.
