Bora Radiator - dead!

[Bernoulli]

So I caught my Bora leaking coolant everywhere last night, coming from the radiator.

It is at a mechanic now for the full verdict but I've had a quick look around at replacements. Here's what I've been offered so far:

New - non-OEM (Nissens) for $275 plus shipping
Used - OEM - $220 delivered
New - non-OEM (not sure of Brand yet, TBA) - $150 delivered

Anyone have any thoughts on whether its best to go used OEM or new aftermarket? Naturally I'd prefer a new one - my car is at 170,000 km's and any second-hand ones will be similar, not keen on buying an OEM one if it's coming up to the life of these!

Would appreciate any advice.

Cheers,
Joe

Mechanic offered me $360 for an Adrad one, his supplier was able to meet that $275 - will be delivered and fitted tomorrow.

Until then, its catching the bus for me!
