I hit the same problem a while back. You can still get "professional" ones at an arm and leg and an array of cheapo type you mentioned but decent mid range ones seem to have become rare. I eventually bought some RS Pro ones. I know that RS Pro stuff is a lottery, but we got some in at work and they seemed solid enough. - You have to stick your own lead and plug on .

So far so good - only time will tell , I guess !
