OK, I've been following this thread for a while now and decided to keep out of it - until now.
WATYF, you're looking for a mic pre, and have $200 to spend.
You've listed a dozen or so that are in your price range, and you want to know which one is the "best".
I'll tell you what: IT DOESN"T MATTER!
$200 dollars is gonna buy you a $200 dollar mic pre. At that price range, the sonic characteristics, and audio quality of most mic pres are going to be very similar.
It's like saying: "I need some butter for my toast. I can choose between parkay, blue bonnet or country crock. One of those has to be the best, which one is it!?"
I vote for saving more money until you can afford something that will be a significant upgrade from what you have now. (Buy cheap, buy twice) If that simply is not an option, and that $200 dollars is just burning a hole in your pocket, I find it difficult to recommend any of these, as I don't own and have never used any of the models you have listed.
But If I HAD to choose one, I'd agree with Blue Bear, and say look into the Grace 101.
