I just ordered the kit today. I ordered it on amazon. Got the Dewalt clamps for the Makita rail guides. I did a little research on everything. The dewalt rail clamps seem to have the best reviews. So, you don’t really need this little doohickey that I saw on YouTube video that I thought I really wanted. It’s TSO’s guide for the rail guides. Just a well engineered little helper tool that is really cool. I wanted it!!! Until I saw the price of it. They have two similar models of it. One is about $159 bucks and the other $179 bucks. Well that ended that idea. LOL!!! I’m a single parent. I just can’t afford that price cause I just don’t want one, it’s better to used two of them in my opinion. Just a thought.
