Cisco ASA ISP and Device Failover


I'm currently researching a CISCO ASA isp and device failover solution.

2 questions:

1) does ASA 5505 support ISP backup/redundancy or only 5510 and higher?  I read a few postings here that have conflicting information so can someone clear this up for me?

2) to accomplish high availability i.e. Active/Active or Active/Standby, does both ASA have to be the same models, i.e. 2x 5505 or 2x 5510?

Thanks in advance!

1. It works on ASA 5505 (but not on a PIX 505)

2. They must be the same model, have the same number and types of interfaces, and the same amount of RAM.

So with a single ASA 5505 I can configure redundant ISP service correct?  Is that with any version of the 5505?
