Buying a kid has the convenience of getting all the wood needed if you have no LHS to shop, so its kind of an added value unless one is very specific about wood selection. A small cottage company doesn't has the buying power as a larger outfit and probably pay the same for their wood as you would at the LHS, they must absorb the cost of waste wood after making these kits and hope to make a reasonable profit for their effort. The real way to save money on hobby stuff is not to have a hobby[&o]
The race to lower prices as already killed many small US/Canadian companies, I consider hobbies in general as a luxury and when I want something enough don't let the price get in the way. I never bought a RTF model as I love building as much as flying, prefer scratch building over kit building because I like doing my own thing and experiment with new ideas. But some kits have something about them that I cannot resist............so I pay the money and enjoy
But in that case $80 for a simple profile 1/2A size is a bit stiff!
