I'm going to check out a Stowa Antea 390 tomorrow. I've wanted an Antea for a long, long time but didn't have the spending cash for a new one, so have been waiting for a used one to pop up locally. A 390 popped up a few days ago and the current owner dates it to may 2006. What's the going service time for an Antea 390? 3 years, 5 years? Should I take that into account when I make a bid, or do these Stowa's run reliably over longer periods? Thanks for your help guys!
