I buy the I, H and other structural shapes at the hobby shop and at train shows. My "LHS", 25 miles away (Mark Twain Hobby Center) normally has a good assortment and they discount it 10% or so. I also buy similar supplies from T and K Hobbies, and from Tower Hobbies.
As luck would have it, there was a vendor at the train show to which we went in Springfield, MO a couple of weeks ago (as part of the Mid-America 3-Railers meet activities) who was selling these and a lot more at 50%, 60% and 75% off! Evidently, the gentleman had bought the inventory of a store that had been hit by a tornado, and paid a minimal price for everything. I bought quite a bit of building supplies
BTW, the structural shapes that I use are the Plastruct ABS, dark grey in color, and are stiff; they are not the white, styrene variety, which is more flexible.
Hope this helps.
And thank you guys for your nice comments!
