It's true, you will never find anything that tastes exactly the same, and nothing at all that works the same way. The gluten is the part of the flour that makes bread possible, because it stretches. Without it, you can get results more like cake.
You need to add xantham gum or guar gum to your flour to give it some possibility of holding together so that you can make something resembling ordinary bread. Even then, it's likely to be heavier than the stuff we have all got used to.
Personally, I gave up on gluten free bread long ago, and tend to just eat Corn Thins instead. They are nice, and not stupidly priced, either.
I just recently came across a new idea, though, for arepas, which is a type of corn bread made in Venezuela from pre-cooked corn flour (only available in latin-American shops, in bags labelled P.A.N.). They look very good, but as I live in Scotland, where latin-American shops are pretty much non-existent, I haven't been able to try them.
