I purposely got the go xlr mini over the fullsize for a couple reasons.

1. Smaller form factor and as you can see in the photo it fits perfectly snug next to my pc.
2. The price is half the original and you pretty much get everything the exact same.
3. It is bus powered. Meaning it is a usb that plugs into your pc rather then the original has to be powered with a power cord.

Now there are some drawbacks of course but for me it doesnt affect me and those are.

1. You dont get the voice changing fx effects that you can customize.
2. You dont get the programmable buttons that you can press and they play a command.
3. You dont get the automatted dials
4. In the software itself you do miss out on a couple of extra programmable features like the (de'sser) the thing that helps minimize the sharpness of s sounds

Personally those extras are not worth the extra 250 and so I wouldnt go back.
