Hey Guys,
I ended up using silver knobs for the filter section (pack of 4 for $17.55) and the "EXT AUDIO" pot since I use these for controlling most of my soft synths; I wanted those to draw my eye a bit more as I use them a ton. These are a bit wider than the stock knobs (17mm vs 13). The filter cutoff knob is obviously the big focal point, and I love the knob I found for that one ($11.79).
And finally, for all the other pots, I found some nice black anodized aluminum ones that come in packs of 13, so I ordered 3 packs of those ($18.99 each). I'm not replacing the endless encoder knobs as it's tough to find knobs that would work for those. I've only replaced the 10 envelope knobs so far, plus the 2 Tuned Feedback knobs - not sure if I'll do all the others yet.
So, the total bill was $86, and that's if I wanted to replace all the pot knobs. If I stick with just the envelope, tuned feedback, and silver filter knobs, it would only be $48 or so. Here are the links:

Cheers!
