Ego 11 is a higher end marker,that have come down in price since LV 1 has been introduced ,second hand £450 or less should get you a nice one with all the bits.
Don't worry about shot count,just condition and service history if possible.
Has adjustable solenoid ,( not that you will play with it much)
Son has an 11.
Etek 4 is still a nice marker,two versions the AM which stands for all metal and a composite one I've not owned one but have fired one,people who have composite say there's no difference.
So it depends if you want brand new Etek or used 11
