They aren't even close to the Griffon Model gates, but those must be assembled one slat by another slat and are a nightmare for all but the most-dedicated. There is also a laser-cut paper version out there. Can't really evaluate these until I see them, but possibly worth the cash if they aren't too expensive.

These are really nice, especially considering the insanity that it assembling anything one slat at a time...I'd rather enjoy my modelling thank you, and not bleed from my eyes while attempting it.
