    Right Angle Drills..

    ..Just wondered if anyone had used a right angle attachment on an otherwise ordinary drill.. the right angled drill themselves are pricey, and since I wouldnt use it much.. I thought the 'attachments' may be a feasible option. They only cost about £20.. I think.. but look a bit 'dodgey' to me..
