This could be a tough one for some! I think my favourite manufacturer has to be Wismec, I just love the style of products they come out with, especially some of their mech mods like the Noisy Cricket and the RX Machina!
Thanks for the replies so far its hard to choose just one isn’t it? I think I could stick by my choice but that doesn’t mean that I wouldn’t find it difficult when something new and shiny came out!
