These new prices are ridiculous

These new prices are ridiculous

I don't need support, per se, I need patches so that I can keep our cluster running for something like two years between OS upgrades.

But the way you make it sound is your cluster will suddenly become useless without updates from RH, which doesn't make sense to me.

If your cluster is well firewalled, you may not need to worry about most of the updates, as they're usually security patches for public services (bind, sendmail, apache, ssl, ...)

If not, then you have the option of applying the patches yourself.
I'm running a customized sendmail on 7.3 (because I wanted TLS, etc., which RH didn't compile in for some reason), so, when the recent vulnerability was announced in Sendmail, I had to patch it myself. Wasn't so bad.
