They are the Swiss distributor for Tresrey and others. I havenīt completed the deal yet so canīt say if theyīre reliable, but the communication seems ok. Also they are near the Austria border thatīs why they can go over the border and ship it with the Austria post. Shouldnīt cause trouble with customs then.
Maybe worth a try?
