The K-30 is an excellent camera, worthy of any of the best Pentax lenses. The DA*50-135 is going to give you better IQ for your money than any other lens I can think of. Even if you could afford many lenses, you should still get one. Buy it, and get a used DA*16-50 (or Tamron 17-50/2.8) if you can manage to later. And if you need a second body, just get another K-30 or K-50. Don't waste your money on a more expensive body which will barely make any difference in the quality of your photos.
