i´m new on this board, so greets to everyone at first

Please excuse my bad english, i´m german and i´m still learning....
This is really a great Page...my Respect, nice Tabs!
I write this poste because i hope someone could help me with my problems.
I want to buy a Western Guitar to Xmas, i think the sound is better than a "normal" accoustic. I started playing Guitar on a Spanish One maybe 2 years ago.
One important reason why i want to buy a Western Guitar is the Sound of the Dave Matthews Band (it´s too damn good...) and i think the Sound of a Western Guitar is good for playing things "like that" (i mean this style/type of music)
Now my question: For what do i have to look for? Which models of Western Guitars are good, i don´t want to pay more than 350 Euros (around 350 Dollars), which one has a similar sound as Dave´s Guitar?
Can you help me out? Is there more i have to look for?
Thanks for answering my questions, have a good Time!
