Buy cheap - buy half a dozen times more like
Thing is the hobby is amazing value - if you go down the Hobbyking KK2 route. You can be all done and in the air for around £150 - which is amazing. If stuff breaks etc it's throw away prices
On the other hand - you can spend a bloody fortune if you go down the quality stuff route.
To learn - go cheap is my opinion. I still think my KK2 wood Quad is the best 'flying' machine I have - it's proper nimble.
