I use a Casio Privia stage piano for gigging. It is comparatively light, I can carry it in its case, on my own and the case has wheels. It is also a lot cheaper than most electric pianos...Anyone who doesn't eat a lot of spinach (like Popeye, so isn't into weightlifting, should go and try one, to see.) It is not the same as an acoustic one but it is pretty close. I will never willingly get rid of my tatty, old, much-loved upright piano, though.
I heard of one piano owner who wrote down info about who had played the piano over the years and kept it in a little notebook inside the top of it. Lovely reading for someone inheriting it, hopefully another piano lover!

Katlaughing...have you got a big house with lovely room for lots of pianos? (Hopeful smile?!) What a great place, a piano sancturary would be, for pianists to visit, entrance fee would be worth it if all the pianos were kept tuned, wow, themed cafe with piano patterned crockery and everything...I can see it now...nope I haven't been drinking, just had a long day...I'll get me coat, (I think I left it on the piano stool...)
