I was looking for a cyclone dust separator and ran across this site. I found one for $17.20 plus about $6.00 shipping. It looks almost like their "expensive " one for $35.00 which has a lot of good reviews. I ended up surfing the site for over an hour. I'm not sure what a lot of the electronic stuff is that they carry but the woodworking stuff looks interesting. They hook you in by giving a coupon with the first order but I think it's a little misleading. At first, you think it's $20 dollars but I think it's actually $3.00 off a $20.00 item. Not sure, Anyway It's a place to waste an hour or so. They also have an interesting box joining jig. On Amazon, it sells for $105 and they have it for $80 or $85 with free shipping.
