You can convert a Low memory unit to a Highmemory unit with a licence upgrade.. They have the same hardware, they are just atifically limited and prices lower.
As far as I know, that is only true for the SRX100. Now, mind you, I haven't actually opened up and checked, but the license upgrade is only available for the SRX100.
EDIT: Heh, now that I posted, other posts stating the same showed up.
