Greg,
Well you know what I got, I think...a MM T50N with all the bells and whistles + power feeder. While it is a very versatile shaper it does take a lot of time to set it up for runs. Tod has the very BIG brother to mine the Formula T1 that is much more heavy duty than mine a serious production machine. For my needs this T50N shaper is way more than adequate as it is a no frills serious heavy duty beast.
That being said if your are looking into making doors in more of a production environment you may at least want to consider a door system. One guy mentioned to me a Weaver door system. It consists of a bunch of shapers set up to do different functions (stiles, rails, panels) I do not think they are very expensive but then again they are entry level as far as what I was told. Many other shops I have seen have many low cost shapers like the Shop Fox all set up for different parts. Some people like the sliding table on shapers like mine (or the linear bearing table on Tod's) but other prefer to use a sled with vacuum clamp hold downs...a personal choice. So you will need to decide to either spend more on one shaper that will be very versatile (but slower in setups) or spend less money on cheaper shapers but need multiple ones.
As far as edge sanders...I just got my EG150 from Sunhill ,can not believe that word came out of my mouth ;>) , anyway it ain't pretty and it is no where built like the rest of my machines but it seems to sand an edge OK.
