I have not had the privelidge of dealing with Nick. I have heard nothing but the highest praise for him, his work, and all things LLoyd. If I was still in the OH area (I went to grad school at Ohio University in Athens...yes, the same Athens as Stewart-MacDonald, and David Messina...in fact, Dave was a grad student at the same time as myself in the same department!!), I would call him in a heartbeat. I would feel honored to both purchase and have the bass setup from Nick. I'm sure you will be very happy!
However, I have dealt twice with Steve Swan. Although he is not a luthier or setup guy, the man he uses is in San Fransico (Jeff Sahs), and he does wonderful setup work to your specs. Steve is wonderful to deal with, and his prices are the lowest I've found.
If you are considering a 180, I would HIGHLY encourage you to step up to a 190. For 5-600 more, you will go from a very good bass to an OUTSTANDING bass, especially for pizz work. My 190 has tonal characteristics that one would not expect from a bass twice the price, or more. I have A/B'd mine with some very reputable expensive basses, and I am more than satisfied with my bass. Nick can get one for you in just a few days. If you compared the 180 with the 190 back to back at his shop, I think you will hear for yourself what I am saying.
Please let us know what you decide. Either way, you will be in good shape.
