OCZ has a new line of enterprise SSDs, based on the SandForce 1500

The SLC based drive should be great as a ZIL, and the MLC drives
should be a close second.
Neither is cost effective as a L2ARC, since the cache device doesn't
require resiliency or high random iops. A previous generation drive
(such as the Vertex or X25-M) is probably sufficient.
If you don't need a high random iops from you l2arc then perhaps you
don't need an l2arc at all?
The whole point of having L2ARC is to serve high random read iops from
RAM and L2ARC device instead of disk drives in a main pool.
