Juniper firewalls - SSG or SRX

[Jeffrey Negro <jnegro () billtrust com>]

Has anyone on Nanog had any hands on experience with the lower end of the
new SRX series Junipers?  We're looking to purchase two new firewalls, and
I'm debating going with SSG series or to make the jump to the SRX line.  Any
input, especially about the learning curve jumping from ScreenOS to JunOS
would be greatly appreciated.  Thank you in advance.
