But for the tubing I went to a local shop called "Affiliated Metals" (801) 363-1711.  A 20' 6061 T6 (2" OD x .125W 1.750 ID x 240") with tax was 48.08 this summer.  It's in SLC, UT and I have no idea about shipping.  But perhaps you can call them and find out.  I then cut it down to 14' so I could have enough spacing/supported area for the tower clamps to the gin pole, but I didn't feel I needed the full 20'.  I can't say that this helped you, but it's at least another avenue to pursue.

I use 20' of 1 1/2" galvanized steel fence tubing.  with a  16" swivel 
arm at the top so it can lower masting or tower sections in line with 
the tower.  It lifts 45G sections with no noticeable flexing. OTOH if 
there is some side force it will spring without bending.  I've lifted 
well over 150# with it with very little deflection. I use a pulley on 
top, the lifting pulley is floating on the rope, and the end of the rope 
ties off at the end of the offset arm making heavy lifts relatively easy.

The only drawback of an all steel gin pole? The thing is "heavy"!.
I understand the quality of this material may vary.  The place where I 
get it (only about a 4 mile drive) has  always had suitable material.

> Also suggested by w9iix, I also decide to buy a 20' of 1/4 wall for heavier pulls.  I haven't used it yet, but it was a lot more (and I can't find my invoice right now for the pricing).  The .125 (1/8") wall can flex, so be aware of that if you are lifting anything heavy.  I was dismantling a 25G top section with rotor and mast and it flexed/bent toward the load a good foot.  But I can state that the 20' 1/4" wall is quite a bit heavier and you don't want to be playing around with it up on the tower much.
