They're not cheap here in Japan ($30-35 USD).
Like most of the Eastern European model manufacturers (Skif, Eastern Express), Maquette's products are a mixed bag of excellence and substandardness. The detail, fit, and overall quality of the moldings vary wildly, even within the same kit.
With a bit of work, however, they do turn into nice models.
So, if you can get 'em cheap, and it's a subject you're yearning to do, I'd say go for it!
