Very helpful answer for the thread starter. Should he buy a LACS, or what did you want to tell us?I think no-one can make up your mind for you. I can tell you my long term experience. I used to be a huge fan of Jems but after a few decades I've started to dislike the monkey grip looks. The PIA looks even worse in my opinion. Also Jem build quality was never that great for the price point in my opinion. I think J Customs are overpriced but getting a good used one sounds like a nice idea.
It's a shame that LACS guitars or similar designs are not available publicly. LACS can make entirely different necks which I think are better than any PIA or J Customs I know of. Of course that's a preference issue too.
