Save a bit of cash, get yourself a low mileage Angel LCD. Does the business every time, had quite a few of them and loved each one.
Good benefits with the speed, if you can afford it go with it, you wont be dissapointed. Very fast marker, light in the hand, and light on paint. With the volumiser and a low pressure setup there's little or no kick, and flat trajectory, very nice.
The reason there are Angel Tech's, any mechanical device will fail, at some time. All markers are prone to wear and tear, and, we are out there to keep the best markers in top condition for you.
All markers will give you trouble, but if you go with the Angel range, you will have exceptional back-up and after sales service, and of-course a tech to help you in case you have a problem.
Good luck with your purchase, and buy british.
