Radiator Opinions (MAC)

[Lawrence C Leung]

Okay,

Let me get this straight:

Advantages of Brass Radiators - repairable when they start to go. 
Advantages of Aluminum/Plastic Radiators - less weight

Does anyone have a comparison of the weight differences?
Does anyone have an estimated life of brass? Aluminum?

I have 163 k miles on my aluminum and it appears it is leaking out an
endcap. Not severe yet, but it's obviously going. Are end caps repairable
(and is it worth the bother?)? I am of the opinion that 162 K and 11 yrs
is pretty reasonable for a radiator to go. 

Finally, any good North East sources for either type?
