+1 to the Riva/Ego suggestion.
Although many will say differently, I've had a great experience with my Ego-T system.
Never really had issues with leaking or dry hits or any of the other "problems". Then again,
I've only been at it for about 2.5 weeks now, so YMMV. If I *had* to recommend a PV
from my own meandering experience, it would be the Ego-T or Ego-C.
