Need help budgeting for EMC VNX support renewal

I've got a pair of VNX 5200 arrays that both have support expiring in the second half of 2018. My budget is calendar year, so in a few months I'm going to need to have a number to plug in for the support renewal on my 2018 budget request.

Problem is EMC won't quote renewals until they're ~90 days out.

I asked my reseller for a "not to exceed" estimate and they came back with $25-27k, which was WAY more than I was expecting.

Both of the arrays are pretty similar. 1 x DPE w/ 24 x 900GB 10k SAS, 2 x DAE w/ 24 4 TB NL SAS, and 3 x 200 GB FastCache SSDs. They're both 8 Gb FC, one has a pair of 4x1Gb iSCSI controllers.

Anybody have something similar that you've renewed support on and would be willing to share pricing?
