I'm not really familiar with HQ, but I would suggest the used, which is larger with SR, right? I bet if your LQS is a dealer, then they are also able/willing to help you with set up once you get it back home and would serve as tech if needed in future. And for a fee they would probably also give you some instruction on it. Most LA companies have split the US into regions with dealers in each region, and if you live in that region they will be your support system regardless of whether you already had the LA, bought it used, or new from them. Good luck and have fun!
