I have a Vishnu DCI that I'll trade for a few big Belgian beers. The filters need to be cleaned, but the adapters are in in good condition and include the clamps. I'm in Cardiff/Encinitas area, and open to other trades, as well.
Edit: I also have a Helene drop in filter (for N54--needs to be cleaned) that's in good condition. Got to be worth at least one big Belgian beer.
