I have an older LX90, pre GPS and LNT. It is the original 8", and it is a fantastic scope. I have just been confirmed as having a permanent disability in my back and I'm really restricted to what I can lift, so although this is over my weight limit, I can manage it reasonably well. And only being a few years younger than you, weight is always a consideration. One advantage of my LX90 over the Celestron, is that there is no cables to trip over or wind around the scope as it takes 'C' size batteries that last quite a while. Aperture is always a first, but also is the feasability of using it comfortably. Why not get a 12" Dob with Argo Navis and a Denver Observing Chair? That is where I'm going if I upgarde, and my 14yo son is more than big enough to help me get it outside!!
