Looks good to me, especially if you just need an HLT. It might be a little thin for a boil, as I'm sure the pot might be a little too thin to give good heat uniformity. However, a lot of us use a lot worse for our brewkettles, so just stir it with a spoon on occasion to keep it from scortching.
Adventures in Homebrewing is a decent company to deal with. They do have some good prices on stuff. That particular pot will be pretty thin for a brewpot. You will have some problems with heat distribution and possible scorching. For the same price you can find thick bottom aluminum pots that will work much better. This is about what I paid for my 10 gallon heavy aluminum stock pot.
