I did a 2×10 to 1×11 conversion last summer. It was totally worth it. I put a 36 tooth chain ring up front and added the Wolftooth 49 tooth sprocket (shimano setup). I lost a gear in the mid range. It gave me the range that I wanted for the speed and the low gear for the limited climbing that I do as well as keeping the effort required from one gear to the next reasonable. The 1×10 will make you sacrifice either the speed or the low gear and the jumps between gears will be pretty noticeable. All in I did the conversion for about $330 and it has worked very well.
