Dm or Ego
I agree, you cant really go wrong with either of the two breeds. Ive owned most of the Dm family but now use an Ego. Its all down to personal choice so if you get the chance try and blag a couple of games with both of them and you will soon find out which one you prefer.
But like i mentioned before both Planet and Dye make some of the best and most reliable accurate markers around. So you wont make a mistake either way.
