I've built two of the scratch build W6NL 40m Moxons.  It performs as 
Dave claims.   It was not an inexpensive antenna to build given some of 
the element parts.  Probably about the same as buying a commercial 40 
and modifying it.  It weighed in under 100#.  A full size 3L will weigh 
2 to 3 times as much or more, so tower and rotator need to be a lot 
beefier but may have the F/B you want.

However, I recently had a QSO with Dave and he said he has a re-design 
in the works to use only the stock sizes of DX Engineering tubing.  That 
would save a lot, rather than searching around from distributors that 
rarely stocked telescoping sizes, although I note that On Line Metals 
now shows many telescoping wall sizes.  DXE has a great selection of 
diameters and wall thicknesses available at good prices.  All of my 
tubing came from them unless they didn't stock it.

##  That is great news..... design it around readily available tubing. 
Dx eng provides superb customer service.  It’s a one stop shop for
tubing requirements, plus other items like the SS  saddle U clamps,
with the solid al saddles.   And esp the jumbo mast clamps, those
things are the ultimate godsend. 

##  They can pack a LOT of tubing into a box, by stuffing mating telescoping
pieces into each other.
