We need a new delay pedal

Our trusty Akai Headrush (E1) is finally starting to crap out on us and we need a backup/replacement.

Here's what we need it to do:

give at least 500ms of delay

self-oscillate on demand

run on batteries

Things we'd like it to do but can live without:

tap tempo (we can always just reach down and turn a knob)

low pass filter (there are plenty of mods out there for this)

stereo output (I know, I know, but it's always nice as an option)

true bypass (again, if we're just talking here...)

Finally, we need something that we can take on stage and not be too precious about. We aren't shunning extravagant boutique delays, but don't want to drop a paycheck on something that we wouldn't feel comfortable bringing to a bar.

Any recommendations??
