As far as Eurocave, I say yes it is worth the cost, as it represents solid quality and reliability. Friends of mine have saved money initially with other units but have been unhappy. Too noisy or the compressor breaks down - one by one I have seen them have to replace or fix their units while my Eurocave units just keep on plugging year after year.
This Artevino unit is nice, but I agree, that the stated number of bottles is never practically achieved. You are looking at 170-180 bottles, max. However, compared to the prices of other Eurocave units (sold primarily through wine enthusiast), $1995 is still a good price.
