I have had the Seyco system for about a year...Pros; small and does not take up space in my small shop, runs only when the saw does, knock out jar catches the bulk of material.........Cons: it is louder than i would like, bags do not last as long as i had hoped. I think it is a little over priced, only useful on the scroll saw not any other tool in the shop...... I will say that when it stops working i will go a different route next time......Hope this helps!
