I apologize if this has been asked before, but I searched through the forum and could not find a similar topic.
I am a complete newbie to Douro table wines, and can honestly say that I don't think I have EVER tried one before.

I have become pretty well-versed in various types of ports over the past year or two (thanks in large part to

), but Douro table wines are completely foreign to me. Obviously, there is a great wealth of information in this forum and in Roy's tasting notes, but I'm finding it difficult to choose a few wines to sample. Also, many of the ones receiving the best reviews are on the expensive side -- or at least what I would consider to be on the expensive side. While I have no problem paying upwards of $100-$150 for a nice bottle of port, I am reluctant to spend a lot on table wines at this point when I don't even know if I will like the style....
Sooooo, I'm wondering if anyone can recommend a few wines that would be good for me to start with (i.e., wines that are fairly representative of Douro table wines in general -- if there is such a thing)? I'm hoping for some that would be pretty readily available on wine-searcher.com, that would cost under say $40 per bottle and that are ready to drink now.
Any suggestions would be greatly appreciated!
