The transformer takes a lot of weight out too and isn't that much effort.
I don't know about carrying a headless, glassless pin up stairs alone, just because of the bulk. Easy with a hand truck, though. Most of mine fit that description and I rarely have any help going in and out of the basement. A $35 Home Depot hand truck does fine.
If you're going to buy one, though, don't get one with inflated tires. Mine has them and it makes the thing too bouncy on stairs.
