Advice on laser cutter?

I need advice. There have been threads on affordable laser cutters before - but this technique develops very quickly, those threads may easily be out of date.
I would like recent info and advice about tabletop cutters - brands, prices, suitable for paper and cardboard op to 2 mm? Size: A4 (letter) or preferably A3 (so more or less double Letter size).
Would be especially interested in types available in Europe.

Hope someone can help!
