Alright, over the next couple months I am probably going to purchase a companion keyboard to keep my PSR740 from getting to lonely (read. something better, although i love the 740) Right now I am primarily interested in the Tyros as everyone seems to rave about it, Yamaha has never let me down, and I want something that will be a major improvement. What I am interested in knowing is, A.) how much should I be able to find this for (in the USA) price wise and B.) should i buy new or used

thanks!
