I went to one in Brienz that had a really interesting collection of cute small furniture items. Unfortunately nothing I could take home on the train back to Zurich

But for someone with a car, it's well worth a look.
Try also 'Brocki-Land' - the more you buy, the cheaper it gets...and it's reasonably well organised. Nothing has a price, but I've only once walked out of there with over 100Chf on the bill, and that was because we bought a heap of snow clothing and shoes...
