3.0D 2005 E83 Radiator NRF vs Mahle

[AUSBMX]

Hi all,

I've got a very slight weep from the RH side radiator tank (only ~ 100 ml every few weeks or so), I'm pretty confident it's the RH tank connection to the radiator core and not the o-rings for the rad hoses (I generally replace the o-rings when I have to remove rad hoses for the first time). I can see coolant collecting at the bottom here, but only very gradually.

It's not really causing any issues, but figure I should get on top of it (it's been this way for ~2-3 years) before there is a more major failure.

I'm in Melbourne, Australia, so parts are not super easy to come by compared to Europe or US. Besides the no-name ebay specials, it looks like my only decent options are an NRF ($250) radiator from Clickable, and a $340 Mahle from runauto. Does anyone have any preference/advice which one to choose? Any advice on disconnecting auto trans heat exchanger?

Thanks!
