Looking for stackable and ISSU/NSSU supporting 12-24 port switch recommendations

Hi folks,

I'm looking for a stackable switch with 12 to 24 ports non POE that also supports ISSU/NSSU firmware upgrades and that is relatively affordable with support worldwide as I'm looking to deploy a stack of them in potential places like HK, NY, EU.

So far, I got:

Ruckus ICX 7150-C12P (12 ports all POE) Ruckus ICX 7150-24 Juniper EX3300-24T Juniper EX3400-24T

So far, the ICX 7150-24 seems to be the most affordable but I'm looking for more options as I've never been too impressed with Foundry/Brocade/Ruckus firmware or support...

I'd like to avoid Cisco is possible but if it fits the bill, I'll consider it.

Thanks for your help.
