If you get put on hold for more than a few minutes at SW, just call back. They will leave you on hold for hours otherwise. Also, try calling early in the morning before they are busy.
FWIW, I did some reading yesterday on octos. Looks like there is a commonly available dwarf octo from Florida that it found regularly when they are collecting live rock from their outdoor aquacultured rock ocean leases. There are a few people selling this octo, for low $ (available on ebay, or direct from the guy who collects them). Looks like it remains pretty small, but tends to be rather nocturnal, so you may not get to see it, or have much interaction with it.
On Tonmo.com there are several article about octos, but it seemed to me like there still was not all that much information about how to keep them. Looks like most people like the 'Bimac' (O. bimaculoides) as one of the best to keep. Trouble is it looks like a 50 gallon system is the minimum for these guys as they can grow to be quite large.
