I can endorse Jarndice's recommendations and cautions, and add that
http://www.rctank.de is, in my experience, a safe site for buying Taigen tanks, and should be one to consider. I have bought two Taigens, and numerous spares from Dominique at rctank, and can state that the service there ticks all the right boxes, in addition to which he has a great range of tanks available in a variety of price brackets, and kit options. Even with the postage from Germany, the prices are competitive. Hope this helps.. and , well, welcome
