This is an investment! That being said, if you only doing one slab, I would recommend DIY build or having someone professionally flatten your project. I would hazard a guess that you would be saving for a fifth of the cost of this rig. I bought the dust shield with vacuum hose attachment and was disappointed on a few levels. Firstly, it's a gimmick that falls short of its intended purpose and although it may cut down a little of the waste being scattered in the shop, it does not work as advertised. Do your slab flattening outside or you'llbe vacuuming for days. Secondly the hose port fit is not standard for any shop vac, so you'll be needing some type of adapter. As for the router sled itself, the build is sturdy, and it does work as intended. However there is the minimal clearance issue. Even at its lowest setting, I still had to raise the work piece as the plunge depth of routers are limited. Also expect to clear debris (constantly) from wheel path as it collects and will hinder the smoorh and level tracking of the wheels Overall, it works. But I'm thinking I should have opted for the bearing rail system. I gave it 3 stars because that's where it falls in the overall rating. Average! These are my opinions from my experience. Your millage may vary. If I could send it back without the hassle. I probably would. I don't have the box, and the return policy says everything has to be in original unused condition, which is impossible after use.
