anyway, the overarching point is that now is the best time to get what you are after, perhaps the best time has actually passed. ie, soon after Supremacy was released there was a big spike in prices as the first stuff hit the market, then when all the boxes/cases were busted there was a big supply of product available as lots of people looked to sell. once this had settled down, many of the lower numbered cards were alwasy going to find their way into collections. I suspect the /25 and /40 cards, particularly of the popular players will soon be extremely hard to come by as they've settled into collections.
basically, if you manage to find one, just secure it rather than haggling over a few bucks.
