I use my local hobby shop wich is in florida . Serpent is the distributor for the us and is in south florida. I havent used the x-shop yet , but i can tell you serpent sucks for shipping and questions. If the part is not available or on back order they dont tell you .... you just wait for weeks on end and when you call to see where your stuff is , thats when they tell you. In florida anything shipped ups is always next day delivery. For some reason it takes up to a week to get stuff from them cause they dont process the order for a few days after they recieve it. I hate to bash a company , but they have yet to satisfy or impress me.
