I'd recommend James of Morningstar FX!
But if I could offer some troubleshooting tips, the last time I had noise on the chorus channel of my VS H20 V2, it was due to the unit being underpowered (I had wired too many pedals from the same power supply). Is there noise when you isolate the pedal?
The V2 also seems to have some issues with older vintage pedals before it. I experienced a "drop" in the chorus effect when I had a 70's EHX Deluxe Electric Mistress before the V2.
