Suitable delay for alpha juno

[barra]

Hi,

I use a Roland Mks-50 for making old school techno. I use a controller with it to manipulate the sounds a lot while performing. I would like to get an analogue delay for under 500 dollars which would suit this synth and which could be easily adjusted during performance - even playing havoc with the sound. What would you recommend?

Thanks,
Barra
