[LAU] control surfaces

hey linux audio users, about a year ago i purchased the korg nanokontrol one when they were dumping them to make room for the nanokontrol II. the last month i'm finally getting to using it for some csound live processing. but im beginning to find shortcomings. for one i could use more knobs. also 14bits of resolution would be nice. finally it would be nice if when i reassign the knobs it would be nice to be able start from the values they are operating on. so im looking into the bcr-2000-b by behringer. any linux users had any experience with this device? any other device suggestions for a budget minded music coder? k.
