Everyone has their own opinion.
It's a price vs. preformance issue to some extent. After that it is mostly personal preference.
I've read one other thread you started and you should notice similar names appearing frequently. Asus A7V133 - Abit KT7A - MSI K7T Turbo - ect.
To make an informed desicion, goto
Toms Hardware or
Anandtech's website. Look around for independant reviews and benchmarks for all of the boards you are considering. You should be able to find all of the above listed boards reviewed against each other. You should also be able to search for 'KT133a' and get a listing of motherboards with that chipset.
My suggestion would be to go for any motherboard with a KT133A chipset. I am sure others have their own opinion. All of the motherboards I listed above sport the KT133a chipset (someone please correct me if I am wrong

) and are all excellent choices for a new T-Bird system. My personal preference is the Asus A7V133 - I have a soft spot for Asus
