if you intend to tote it around at all (ie like inthe trunk of a car), i like the schutt travel tee. not great for younger ages thought, as it does not drop down very far (Ok for say 9 Yo and up). when I bought gear, one consideration was everything had to fit into my trunk, and be easy to tote from car to field and back.
Get a tanner tee. If they are out get a tanner tee. Get the short one and when you need more height go to the plumbing section of any hardware store and get a 12" pipe threaded on both ends. (They will have a bin full of exactly what you need.)
When you get a bow net type net the base of the tanner tee unscrews off the stem and fits right in the bag.
That's the thing! I was thinking it was all one piece but now I remember the coupling. I cranked her on there with a pipe wrench so it would always come off the right way.
