Okay, let's be serious now.
Sneaking is still too cheap, caps wise. Here are my thoughts on the general subject:
Sneakers equipment is generally cheaper than a full blown combat character. Full sneak attire is probably around the 2k caps mark. (you can farm most of the weapons, wakis, automags and Metba(?) and just need to buy armour and a stealth boy). Stealth Boys are too cheap I believe. Full Combat character should be around 4k.
Gameplay wise - it is generally easily to counter - a wise man once said, ''why go to the core alone?''. If you are worried about sneakers, why do you wander the pvp area alone? Ask a buddy to go with you.
Since the needler has been nerfed, sneak has lost a lot of its ''wipe period'' power.
