Portable Redundant Power System for Catalyst Switches?

Does anybody know if a portable RPS device either from Cisco or another manufacturer exists, that would allow you to move primary power for a switch without causing an outage? I realize that for the Catalyst 3560 for example, you can get an RPS 2300 or 675, but my understanding is that these are made for a more permanent installation, not to mention rather costly. Thanks in advance for any tips.

EDIT: It looks like the RPS 675 is rather inexpensive after all, especially in the secondary market, but still rather large for toting around.

If I remember correctly, the RPS will fail over from primary power to it but it requires (?) a reload to get to back on primary power.  I.e., if I'm correct, you'll still have an outage trying to move back to primary power.
