Hi, i want to remove my one month old huge side calf tattoo, its about 180cm2, dark black, lots of outlines and shading. i have choice between 4 different clinics and their laser systems, its medlite portable, spectra vrm iv, alma harmony xl. they are for the same price, and there is also quanta q plus c system which is much more expensive. all of them q switched nd yag. are there some differences, or it doesnt matter? thank you for answers
