We started using the KTI KGD-802-P managed GigE PoE switches. 8 ether (4 w/PoE) with two shared SFP ports. They will power ePMP, Rocket Titaniums, or other 802.3.af equipment. We pay around $450 for them. They are hardened and require 48V. Planet makes some that will run 802.3af equipment with 24V or 48V power but you'll need to use their SFP modules.
