Yeah those were great, as well as the Hardwire pedals! You can pick up a Digidelay for under $50 and they are every bit as good as a Boss DD-X for twice as much. All of the X-series seem to be good deals on the used market.
They were the best thing you could get if you were in middle school in 1999. They're okay for the money but there are a lot of better alternatives these days.
I have a Digiverb. They aren't bad at all and can be found for good prices these days. They aren't nearly as full-featured as something like the Silver Lake, but don't really try to be.
