Overhead Table saw blade dust collection options?

[kooshball]

Looking for suggestions regarding dust collection from the top of a table saw blade.

I have a sawstop and have used my festool dust extractor hooked to the blade guard which has given me decent results but I am getting my new shop space setup and now have more options. The main drawback to continuing the way I have is that when doing thin cuts, dados or non-through cuts I give up dust collection above the saw blade.

I see that sawstop, shark, grizzly and others make over-blade dust collection setups that are separate from a riving knife which expands its use to dados, etc. main question is which of these over-blade options are the most effective at collecting dust and also being user friendly.

All suggestions first hand experiences are welcomed.

Thx!

I have a Sawstop with the over arm that connects to the blade guard. Probably gets 95% of the sawdust. Unfortunately can't be used with the riving knife alone, but that is seldom done. Promotional give away two days after I bought mine, I sent Sawstop a letter requesting I be included in the promotion. I got no response but lo and behold about three weeks the big brown truck dropped one on my porch. I really like this saw.
