Found a good source recently for some cheap wire over at Fusion Beads. Of particular interest is their offerings of artistic wire and parawire. I'm still not sure of the difference between the two just yet, though from what I've gathered from the internet one is a softer wire while the other holds its color better. Only some time behind the vise and in the water will tell what the true story is, meanwhile, if you're sick of paying over $3 for a 7 yard spool then check this wire out.
Available in more colors and sizes than what Ultra Wire has available, 30 yard spools of artistic wire ring up at $2.99 and 50 yard spools of parawire come in at $4.49. Better yet, there is no minimum order required and free shipping! I know there are other places out there that sell wire at a cheaper cost, but Fusion Beads actually had all of their colors in stock, and free shipping can't be beat, especially for a $10 order. I always have a problem with joints that charge more for shipping than the cost of the items ordered. While the red wire differed in color between the artistic and parawire varieties, that isn't the end of the world. The magenta wire I ordered is hot. I'm impressed with the colors and quality of the wires and will be ordering more in the future.
P.S. If anyone has a source for wine or claret colored wire please let me know. Then my quest for world domination will be near.
