BEHR vs NISSENS Heater Core?

[satyr]

Hey everybody-
The 87 190 2.0D hasn't been driven now in almost 2 mos because there is such a serious coolant leak under the dash now. The floorboards are sopping wet, the windows fog, and its impossible to drive it this way. So we're budgeting for a new heater core.

I need to place the order asap- so which would be the better heater core?

The Behr doesn't come with o-rings or anything, where it appears the Nissens has o-rings and some sort of adhesive-backed padding.
I don't know if the Behr is significantly better than the Nissens anymore but I found the Behr for $100, the Nissens for $140 plus shipping.

What do you suggest? Thanks for the help- John
