Marktplaats seem to have plenty on offer at the moment including an 820, a Pontos (seemingy always difficult to source) and a couple of Futures. This link gives anything marked Eriba, so includes Feelings etc, but it's worth sorting the wheat from the chaff..

Ordered in price high to low...

Edit: Ah, not sorted on price, the pasted link seems to ignore that bit...to do that, in the top right hand corner the box marked 'Sorteer op' should be set to 'Pris:hoog-laag' or whichever you choose...

We bought both of ours through that site, we found the Dutch venders very helpful.
