Hi John and welcome. I found my 12" gso/bintel dob to be very good and this seems a common opinion. I would think that the main advantage of building one would be the portability of a truss design. Mind you, the 12" GSO is not too much of a problem to move around.
There are some lovely truss dob designs around though. Price wise you would lose little to buy a GSO dob and building a new assembly for the optics if it takes your fancy or you find the tube set up cumbersome.
Whatever way, I reckon you'll have a good time.
