Since NS only sells to vendors they could only provide the wholesale prices (which I don't believe any wholesaler would post that for the general public).
The Fausti models that NS supplies is the Conrad line (5 models (Conrad, Conrad Extra, Conrad Deluxe, Conrad Sporting and Lady Conrad) not sold in the US so difficult to find any info at all on the net but pretty much the specs of the US Caledon models except the Conrad's have a schnable forends, except the Deluxe which has a prince of whales style stock/splinter forend), two of the Class models (Class and Class SL - info on US site) and two of the DEA side/side (DEA/DEA SLX - again, same as on the US webite).
The Conrad line would generally retail in the $1700 to $2450, The Class in the $2600-3150 range and the S/S DEA's would be on the shelf for $4000-5700 using industry standard mark-up's based on wholesale.
Of course if you shopped around you could probably shave a bit off the prices.
Those are part of Fausti's (production line) models. If you want "fancy" you contact the company and work out the details with them.
