Question....??!!!

hey there how've you been ?
so i need your help about coloring. As you may have notice (or not XP ) i am currently using Photoshop to color my drawings. My problem is that i don't have a tablet so to color something i need to scan it and then color it ,using my mouse. The problem in this is that even though i do get to color it the lines are too thick or too black and sometimes it ruins the whole image. So i was wondering whether SAI is better and easier to use ...and if not do you have any suggestions to help me ?
