Ryan - I'm not really ready to go with hard ducting so was looking at the tubing (just grabbed that kit link as it was easier to note the tubing).
The Powertech
gate looks similar to the gate on
Oneida but may have extra features, or just better marketing.
On a wider view - do you find your SC to work well through the range from large to small (even hand held) tools? That's one of the features that makes the SC attractive.
