The wine that GMT mentioned was '78 Leroy Puligny-Montrachet Champ Gain. Champ Gain is, I think, a premier cru vineyard in the Puligny-Montrachet AOC (someone with more burg expertise please correct me if I'm wrong). Also, '78 was a classic vintage.
I bought some of that wine for $25 on clearance sale. The store, Premier Cru in Northern Cal, was selling it cheap b/c they were having problems with bottle variation. Ordnarily, I think that wine would be more like $80. So far I've opened two of the bottles -- one was off, the other was amazing. From my very limited experience, good aged white burg is in a class by itself.
The Puligny-Montrachet VM found is just the village Puligny, not a premier cru. Also, '91 was (according to WS) a so-so vintage. So, even at its best, that wine is not gonna be great. Moreover, I don't know much about white burgundy, but I don't think these village wines are generally made to last a very long time.
Obviously if it's no good, VM is only out $4 so it's no big thing. But my experience with the Leroy was so great (at least the second bottle) that IMO it's worth spending a little more to see what all the fuss over white burg is about. Maybe not $80, but buy something decent so you don't have a bad first experience.
North Berkeley wine has a pretty good deal going on some white burg right now. Check it out: http://www.northberkeleyimports.com
