Generally speaking, I will get WEN over HF any day. The WEN power tools are a big step up from HF. I have the smaller WEN dust collector, 3401 12-gallon, that I recently mounted on a wall and am working on connecting tools too. Mine is going to go through a Rockler cyclone dust separator. I have a small shop and will only be pulling from my table saw, router (attached to table saw), miter saw and a oscillating sander. Will only be running one at a time so my needs should be covered.
The cyclone will keep the larger bits away from your system to reduce chance of clogging but as mentioned, it does affect the overall suction power. But the WEN should be more powerful than the HF overall and shouldn't hurt your collection too much. It is a reasonable cost and worth the shot and at 2HP, the WEN has more oomph than many other brands in this price point.
There are a lot of video reviews on the WEN tools but this seems like a really good bang for the buck.
