So anyway Im thinking about buying one of the Guitar Rig software suites from Native Instruments... my question is

Do I have to buy the $200 foot pedal thingey (or package)?
Can I just buy a 1/4-USB, for examplehttp://www.musiciansfriend.com/product/Behringer-Guitar-Link-UCG102?sku=241228,
and the software?

Please if anyone has any experience with this software (err well software family) and this set up that im suggesting give me some feedback...

Also if anyone has hands on experience with this product and can recomend another product of equal or better quality... preferably one that isnt as expensive

Thanks in advance
