for improved digital delay with good modulation consider the more affordable classics (like a PCM41 over the better known 42 :-). I like the following (only one's a pedal because it was reissued for guitarists and its great):

and this guy, which is my secret weapon:

but don't tell anyone about it...
Roland also made some delays that were directly comparable to the Korg and had SOME of the features of the Toa, but the Korg soudns more musical as a delay whereas the roland's a bit thin and tinny and the korg instrument preamp is better. That's the mid-period U2 sound.
Its just impossible to make anything but a bare-bones digital delay in a stomp without resorting to USB connectivity. The toneprint phone app somewhat bypasses this if you don't want to edit patches yourself, but in digital delay-land I just feel 19" rack is king and worth exploring. Either that or get something with a bigger pedalboard footprint in the now ubiquitous Line 6 format.
Delete this post once you read it, I don't want Toa's to become expensive because I would really have a whole rack of them.
