While I cannot judge all kits from the artillery series, this is my experience:

Even I was able to produce an acceptable result from A014 (Long Tom, painted as a WW1 French gun) and A015 (Schneider 105mm howitzer), so can you. I did change the wheels of the Schneider gun for more common ones, and replaced the shield which is too small IMHO, but everything went together easily, the "instruction" pictures on the boxes' back were sufficient, and the plastic can be glued with standard modelling glue. Add the excellent crew figures to that, I cannot see what's not to like.
