BEST BRANDS FOR CONTROL ARMS?

[caseypayne]

I'm wanting (needing) to replace all four front control arms on my 159 wagon.
Not knowing anything about auto parts I'm just looking for any advice on reputable brands that I should go for. I've managed to get my hands on 3 of the 4 arms from a european parts dealer here in melbourne, borg & beck brand.
Can't find the elusive left hand upper in b&b, but I've seen plenty available from other brands - delphi, trw, etc.
Is there anything wrong with mixing manufacturers?
Any advice on what brands to look for will be hugely appreciated.
