I'd go for a Shure SM58.
For about $100 you'll have the world's most used vocal microphone. Countless hits have been recorded with the SM58 and most if not all rental companies use SM58's.
If you want to cut down on cost: do it on the popscreen. You can easilly make your own with a piece of electrical wiring and a nylon stocking.
