While, buying new will give you a warranty etc, many on here would argue that it would still benefit from a proper setup to get the action how you want it etc etc. So this in turn adds more money into the mix. I would personally get looking on eBay or here, or contact your local high schools in the area. I picked a full 4/4 DB for £50 from a school! Just needed a sound post re-sit and the bass was up and running again! Obviously, buying unseen from eBay is a bit hit and miss, but if you can get a good bargain a bit of money you save could be spent on getting it set up properly. It's a funny balancing act, each with pros and cons. I'm sure more learned members will guide you better than I will though
