I picked up the base 21" model for my wife yesterday and have a Samsung SSD arriving today. Once that gets here I'm taking the still boxed iMac and SSD to a nearby Apple Authorized Service Provider who will install the SSD plus more memory themselves which will enable me to not break AppleCare or warranty. That way I know the machine will be viable for a long time to come and still be serviceable. Might be something to look into if you're wanting to add SSD at today's cost and for significantly less and still have support in place. Check with your AASP before you take the plunge though.
