If it's the old regular one, don't expect anything more than 20 bucks. As for an SP, I'd say around 30 bucks would get it around (40 if it's in mint condition)
The progamers I use to sub for me were (in order):
1. Siz[Kal] (The guy relaxing in a chair) 2. n.die_Jaedong (The guy with the thumbs up pose) 3. Firebathero (The moderator dance guy. This is the dude that shows off a lot.)
