Graupner servos are a top shelf product that compete favourably with the well known brands like Hyperion & Hitec. The Graupner DES707BBMG is a great example of quality and lots of features at the price point of a more standard hitec. I personally use the Graupner servos, in fact my 2 metre SeaFury has DES707BBMG right through it, even the gear doors! Super smooth, high torque, good speed, you can see the quality of build in the casework and the gear trains are tight and accurate. DO yourself a favour and don't drop huge $$$ on a digital MG servo, try the Graupner, you will be surprised!
