All three markers are well worth getting, if you can afford it go to an angel lcd or better, next in my view would be an impulse, and last but not least the timmy.
The angel lcd is best buy at the moment, and has a fantastic spares back up system, you can get parts from literally everywhere.
Impulse, good straight from the box, needs a bit more speed though, spares and upgrades easily sourced.
Intimidator, a bit less popular than the other two but still a good piecs of kit.
Final answer = Angel LCD
