You won't even be able to get one bottle of Vega Sicilia for that budget, unfortunately. A bottle starts at about 140€. The winery has an "economical" line called Valbuena which costs "only" 70€. Both are great wines, but maybe a bit steep. The Alion I mentioned before is a separate winery but it belongs to the Vega Sicilia Group. It goes for about 30€. Protos is always a good bet too.

I've never tried the Remelluri, but the wines from the bodega are highly rated, and we have a taster to back it up? I tried to find it, and I see there is a 1997 Remelluri called "la Granja", and it goes for that price. Is that the one you were talking about Gregorio? I'll have to keep an eye out for it myself.
