I hate that the SWM can only support 8 tuners. I'd like to get a HD DVR for my bedroom to replace my H20. I need 9 tuners so I guess I need to upgrade my 6x8 Zinwell switch for the 6X16 model.
The SWM supports 8 SWM tuners and has three additional legacy ports, so you can squeeze up to 11 tuners out of the SWM. Additionally, you can use four ports off of the existing 6x8 to feed the SWM and have another 4 ports left from it. You could then run a total of 15 tuners from this setup (1 shy of the 6x16). Bottom line, go for the SWM8...
