I'm not in position to do a major reno at the moment (time nor energy).
My wife has brought up external insulation as another option - I'm not sure the pros and cons of that.
Has anyone who has gone the blown in route offering any advice? Other suggestions?

My parents had an old bi-level with the same problem. The insulation was paper thin.
Tore the drywall off all the exterior walls and replaced with roxul insulation, then redrywalled. Ton of work, but I think worth it. Took the insulation that was in the walls and added it to the existing attic insulation.
I'd almost take it one step further and add 2x2s onto the studs to make the cavity bigger. Yes, you lose some space in the house but that coupled with new windows and you basically have a modern insulated home.
