Well, depends on when you want to upgrade. I'd say if you're pretty sure you'll be upgrading then do the dance. DDR isn't going to get much cheaper. And as soon as the summer swoon ends you'll see prices go up in fall as they always do. Personally, I'm going for an nForce mobo and dumping Intel ASAP (ie August when the mobos are released hopefully). Knowing this, I think I made a smart move by picking up 512MB of DDR PC2100 from crucial for $120 (that's something around 20 cents a meg - sick). So if you're not sure, it's a much tougher call. Only you know the size of your bank account.
