So I did a search on Take2 and I found many different brand of the Guitar Link usb interface.
I know the Behringer one comes with software, but I already have Guitar Rig installed on my PC so I dont really think theres any benefit to getting the Behringer one especially since the Behringer one is R615 and the Brainydeal one (1 of the no name ones...) is R347 and they seem to be exactly the same product other than having the name Behringer on one...
Specs seems the same on both of them and judging from the fact that they are so identical i'd say Behringer probably bought them and put their name on it and are now selling it at a higher price...
Its nearly half the price :O
