If 300 is the budget, you might as well save a bit more and fork maybe 350 for a DD20. It's got stereo delay, 4 presets + 1 manual, footswitch control option, a big ass LCD screen so you know exactly what tempo you're on, and a whole lot of other options.
The other big contender is the TC electronics NOVA delay. But that one's gonna cost a little more. Check out the pedalboard thread and see how many people are adding these 2 to their rigs. Definitely value for money.
