[j-nsp] SRX240 - ready for prime time?

[TCIS List Acct]

Over the past few years the general feeling I've gotten reading j-nsp and 
elsewhere was to stay away from the SRX line until the code matured.  We've got 
an upcoming project that I'm considering using a SRX 240 for.

Has the code matured to the point that it can be considered a stable platform 
for security (just basic firewall, 1:1 NATs, maybe a few VPNs), high 
availability, and some very basic layer 3 routing services?

TIA.
