First off, let me say thanks to Mr. Hersh and all the members who have made this site such a wonderful place to learn about port.
I occasionally splurge on a vintage port or 20-year tawny, but my current budget doesn't allow for everyday drinking of such ports. I was wondering what others here might recommend as an inexpensive, everyday kind of port. Here are a few of things I am looking for just to give you an idea:
1. Inexpensive (say, under $20. The lower the better :) )
2. Able to last at least a couple weeks after opening.
3. Not a tawny (I like tawnies, but prefer the "redder" types of port)
Currently, my "go to" port is Noval LB which I can often find on good sales for around $13. All opinions and recommendations are appreciated. Also, if you think there is nothing worthwhile that fulfills my criteria, I would love to hear why. I just need something to get me by until I can save up for a few cases of Nacional.

Thanks,
Michael
