So Im looking to buy an ASA. I bought the CCNA:Security lab manual (1.1). It's using the ASA 5510.
Do you think I can get away with using the 5505?
I've searched on the websites for the differences- but all I can discern is that the 5510 has an IPS module. ...which in all fairness isn't any different than what the OCG is telling me.
The difference (used) is just $1000. Ya know.

Edit: Comparison-
