Planning on buying a bass (RI Mustang) and I've already tried it several times and know how it feels. I basically have several options to buy: 1) Buy from a local store for $840, but with 10.25% sales tax (but I get to try it out first) 2) Buy online from GC or Musician's Friend for around $750 and have it shipped 3) Buy used from GC for around $500 and have it shipped What's best here? I can save money buying used but there's the issue of quality. I could buy new but then I can't try the specific instrument first. I could buy from the local store but suffer the high taxes. What does everyone think is best here?
