Omf, Sorry to hear the D020-W are gone! I love mine! (I believe me LHS still has a D020-W in stock, though they're asking $165 for it
)
Ya know, have you considered buying an Ash-Catcher and pairing it with a nice J-Hook? You could get the sidecar action you want, perfect 90 degree action for no neck pain, and you could choose any sort of perc action you want! Hell, AC's are cheap enough you could buy several and switch them up!
(full credit to
@ataxian for the idea of using a J-Hook with an AC)
(Sadly this AC is no longer amongst the living, snapped the blue neck when trying to catch it mid-fall! - never hit the ground, the sudden decrease in velocity from catching it was enough to break it!)
Edit - or you could get a custom Solo Female GonG made by
@VaPeD&CoNfUsEd to fit your D020--2-w
