I think that if you want survival and a good cup run you should go for Andy Johnson of Fulham,for what say 5milion,what a great buy that would be.
All that matters for you is survival and then survival again next season (second season syndrome). After the 2nd season it gets a lot easier and you can follow the Fulham/Bolton/Stoke blueprint. I know many QPR fans don't rate AJ, that may be because he is from rivals Fulham but he would guarantee goals even if he is just a stop gap, it surely has to be a better option than Bothroyd. AJ can keep you in this division, and then you can push on
