I have seen at either Lowe's or Home Depot a Square-D product that is 
designed for this purpose but appears much heftier than those crummy 
Generac things.  It uses back-to-back 220V breakers linked with a permanent 
mechanical bracket such that one must be off when the other is on.  someone 
wrote me telling me that he used a 200 amp breaker on the leg that handled 
his entire house current, and a breaker sized to his generator on the other 
side, which would somewhat help to keep the cost down.  The Square D unit 
comes in a box that is punched for breakers for selected circuits to be 
connected to the generator (following the apparent code restriction that it 
not be possible to overload the generator), but I don't think there's any 
practical reason why it couldn't be set up to feed your entire house panel 
instead.
