[j-nsp] virtual router, M or J?

[Jensen Tyler]

I have deployed a SRX240 with DC power.

SRX seems to be a really good candidate. It looks like all models have
almost identical features, the only difference is performance. I will buy a
SRX100, maybe even 2 to test high availability.

Customers may have overlapping address space and the virtual router may
interact with their CPE routers too.

The only issue is that it doesn't support DC power and can't be deployed in
some cases.

J-series seems much more expensive and doesn't have nearly as many features.
DC power is available though. Just wonder what's application?

M-series seems really over priced for this application.

Thanks,
