Hey guys I'm trying to get a home studio going here. I mainly play guitar so of course I want an awesome interface to work with. So far the best options appear to be the Line 6 Pod HD Pro Rack and the Avid Eleven Rack. Both fairly pricey and I wonder if they're really worth every penny, nickel and dime that may or may not have gone into the making of them. I mainly play Death Metal, however I want it to be versatile, covering my acoustic projects, garage rock, etc. I also would really like to be able to record bass, an electric ukelele, and an electric mandolin through the interface as well. What do I buy??
