A few months ago, I changed my Toyota Radiator to a Denso brand. I regretted after realising that the price is more expensive than Toyota's. If only I take the time to drive to town to search for one; I would save a lot of money! But it is too late now.
If you are looking for any radiator for that matter, why not look for it online first; especially if you are living in US. Radiators.com is the largest radiator distributor in the US. Their warehouse shelves are fully lined with over 60,000 different radiators and ac condensers. I am sure their prices are very attractive too.
