I have used MTS twice and have been caught by Customs/PO both times. Their small details are wonderful. However beware of their kits, missing parts are a frequent occurence and it is very difficult to prove to MTS that they are at fault. Last time instead of replacing missing parts they suggested I wait until I ordered more stuff from them - that is not going to happen! Many fellow modellers on www.kitforums.com agree with me that their customer service sucks!
