Facebook might hate freedom, but it's still going strong here.
Depends really, the ARES is going for less than 200 on some sites, like redwolf and WGC:http://www.redwolfairsoft.com/redwolf/a ... odID=17883http://www.wgcshop.com/wgc2008/main/pro ... atid=&cat=Depending on the condition and accessories you include you could probably get 180-200 at the MOST. With just the gun, mag and battery, more like 140-150.It is a discontinued item, which makes it rather rare, but that really only comes into play if its in perfect condition.
FYI You do know that Ares UMP does not use the same mags as your G&G, don't you?
