Best repair panels and sheetmetal

[Nixon]

I read a thread on here the other day about the best air induction hoods and who made what and how there are only a couple of manufacturers but many retail brand names.

My question to you guys is this: Are all sheet metal repro parts and patch panels equal.

LMC admits their stuff is from oversees and I may be reading into it, but it seems that ECE is saying their stuff is American.

Who's metal do you guys recommend? I just ordered edfabman's DVD series and want to start purchasing the metal to go with it. I know there are other retailers out there like Classic Heartbeat and GMCPauls as well as others. There are too many choices and I want to learn from you guys experience.
