USA can't change to metric. First of all, they would have to change almost evey single street sign, text book, change spedometer numbering (flip it), and not to mention educate every citizen, because almost no one I know knows metric. We have been told to learn it for generations, and there's been no change yet.
In other words, big time, and big money!
I'm sorry, but hundreds of other nations, many with MUCH larger populations and MUCH less money, have converted. Saying that the US can't because it's 'too hard' is plain and simple a cop-out. You are talking about one of the most advanced and powerful nations in the world. Metric conversion should be far easier for the US than any other country, and quite frankly as one of the world's technology leaders they should have done it years ago.
The USA can put a man on the moon. The USA can lead the word in semiconductor research. The USA can create some of the most widely used and most important software in the world. Yes, USA can change to metric. I have great faith in their ability to do such a task. It's a shame their own governement does not.
No, it's won't happen overnight. You won't go to sleep Sunday night and wake up Monday morning, and all your systems are changed. But quite frankly, the little things that could get the wheels in motion need to start now, so that in 10 years things are fixed.
Two posts ago I said I wouldn't get on my soapbox. Now look at what you've made me do.

Apologies for the offtopics, kids.
To the original poster:
My first cabinet used routed edges. The cost of t-moulding is too great for me, basically because the shipping costs 5 times what the actual t-moulding would. The routed edges look nice, and don't get damaged. Plus, they are kiddie safe, and don't hurt as much as sharp corners.
My second cabinet will use t-moulding. I managed to go in with a few locals on a group buy, which means we split the cost of postage to something more reasonable. I've only just recently cut the groove for the t-moulding to live in, so no comments as yet on whether or not the end result is worth the effort. One thing t-moulding has going for it is the colours. I'm following Blakey's design, and making a black cab with chrome t-moulding. I'm hoping the end result will look pretty cool.
