IBM Wheelwriter 6783-2?

[chzel]

I can get a Wheelwriter (IBM 6783-2)for ~40€ locally.
Does anyone know if they are easy to repair or how robust they are?
I guess ribbons should be somewhat difficult to find?
I know I can use the Code+Spacebar and the flippers and single-piece keys, so I think I'll get it, but I'd like to hear your opinions!

The price seems a bit steep for just the keycaps. Somebody over here or on geekhack converted the keyboard unit to an actual usable keyboard, the layout is a bit weird, though.

I am hoping it will work as an actual typewriter and I'll haggle a bit, so salvaging the caps will be a last resort!
