Dye is American with Proto being their sister in the making, however Dye does have a main outlet in the UK in Croydon Surrey. Proto haven`t come out with a good gun since the PM8
Planet Eclipse is in Manchester with everything hands on within their premises.
Dye is the top gun with Proto being the cheaper version of Dye, that`s why they have that ergonomic designed grip shared,
where Planet have as top of the Range + Ego`s and Geo`s as the Top end , then Followed by the Etek`s ( which are really good guns, where the Etek 3 = an Ego 9 ) these are followed by the Etha which really came out as a woodsball gun = strong and sturdy and robust but with a harder hit on the balls.
Empire is American with the AXE now leading the front within the Pro levels = great gun , shoots smooth as butter and leads the other makers for dust as far as quietness of the shot is concerned.
Bob Long is American but only does top of the range guns = One word for these is = Beautiful , again these come through the back door.
Machine = New company , does a fantastic gun, Top End only, very expensive, and Not worth the money they ask for, in fact these are being sold off for a third of the retale price at the moment, which is telling everybody = Not worth a carrot.
there are others but you can see what I mean about thinking about Planet Eclipse in particular.
