I just ordered stuff from them. Seems like a great company. They replied to my emails within 2 hours and took the time to answer all my questions. He also guaranteed that once payment was processed all my parts would be shipped out within 3-4 business days. They are off to a great start. I hope ASB crashes and burns, they honestly caused me nothing but headaches.
So far TS-One doesn't seem to have much in terms of replacement parts, but they have quite a few interesting mods. I've purchased the steel nozzel and increased recoil parts.
