You'll notice I didn't say "buy", I said "use".
I'll start by saying that I don't need another cross cut sled. I've made 2 of my own, a large one and a small one. They work perfectly fine.
The only thing I'm curious about is whether or not there is anything inherently wrong with the Rockler Cross Cut sled. Yes, it cost $150. Yes, the drop-off platform is another $38. Yes, it is constructed of materials known to be harmful to residents of Califormia. But you don't have to pay for it and you don't live in CA. (Well, most of you don't.)
If someone *gave* you a Rockler Cross Cut sled and drop-off table, is there a specific reason (or reasons) that you would forgo it's use and continue using your home made sled, other than the emotional attachment to your good ole sled?
