Yes, always disappointed when a plastic cork is revealed, a lousy glass usually follows, followed by pouring the rest down the drain.
Of course, 4 or 5 Euros in France usually does the trick for table wine (with a real cork to boot); imagine in the States the same bottle will run $25+
You can usually find decent French wines in the States for $12-15 if you shop at the right places. Most wine specialty stores tend to overprice (and at restaurants they'll easily run $30-50).
I don't like the plastic corks myself, they seem inordinately hard to pull out of the bottle.
