If you've read terrible things about any clinic from multiple sources it goes without saying you should cross them off your list. As for the WAW , it's not a technic, it's an implanter pen invented by Dr. Jean Devroye. It's a good pen but all implanter pens can extract multiple follicle grafts by changing the tip, so yeah that's complete BS. Anyway, if price is your brick wall, you probably can't stay in England. Bisanga has a clinic in Athens that I think that may match your price point. Or you can look in Belgium which I believe is generally less expensive then England.
