Well if you do end up getting the China Maus, i'd love to hear all about it, quality, if it will last, how its shoots and so forth, because if it is actually made well, it's certainly an interesting weapon.
And if you get the Tanaka, remember to get an elongated nozzle, or make one yourself if you must, the standard nozzle is rubbish, doesen't push the BB into the hop unit like it should, making for terrible groupings, but it shoots like a wet dream with a propper nozzle.
You might allready know all that, but just passing on the word in case you or others dont.
They dont look like mine out of the box though, they are blonde wood with a lackluster varnish job when you buy them, hence the need to do some wood work, with just a bit of sanding down, recolouring and a new coat of varnish, they really do look stunning
