Layer 3 Switches

For this project I'm married to Cisco, but may not be in the future. 
I've worked with Dell's PowerConnect line, but found that the feature set
was 90% of what Cisco had, but it ends up being really frustrating when you
need that last 10%. They also haven't seemed quite as mature as the Catalyst
I've liked the price of the Ubiquiti switches I've seen, but haven't gotten
to play with them, and based on their EdgeRouter line, am not sure about
their maturity either.

While I can't speak for Cisco, L3 usually comes free (software licenses 
notwithstanding) from most vendors these days.  The off-the-shelf 
silicon generally handles it along with L2 switching.  I'm not sure if 
you can "turn off" the L3 features in IOS XE (which the 9200s run), but 
you can of course just not configure them if you don't need them.

Are you married to Cisco?  The 9200 is not a bad pizza box platform, but 
you can definitely get comparable features and bandwidth cheaper (or 
more bandwidth for the same price) from other folks.
