How much do Glock 9's range from price wise in the states?
Since there is no "9" in the Glock model numbers, I will assume that you are talking about a 9mm. Glock has (from memory, from smallest to largest) the G26, G19, G17, and the G34. I have a G26, two G19s and a G34 (practical/tactical). Glock also makes the mythical Glock 18 which is a full auto version of the G17. I have shot one, they are a fucking pain in the ass.
The G26, G19 and G17 all run about $500 new. The G34 runs about $600. The G34 is the BEST gun to run a suppressor.

Here's a bonus video of me running a suppressed M16 this past summer:
