You can safely underfill a HP tank (that is about the same physical size, yet lighter) to get the same amount of gas a fully filled LP tank of similar dimensions gets you.

I agree with this. I have no problem getting HP fills at my LDS, so I have HP tanks. I would not want to keep pushing my luck or the luck of the Tank Filler for overfilling a LP tank. All though they have a pretty good track record in Fl where Overfilling LP tanks is fairly common. I still would rather fill a tank to its rated pressure. If I do not need a ton of gas I just tell the person filling my tanks to take them to about 3000 or 3100 and stop. When they cool down they are in the 2700 range which is still plenty of gas (HP 130 & 120's). If I want a full fill I usually leave them there for a few hours so that they can cool off. If I do not have a few hours and I want a pretty close to full fill they just fill them super slow. I personally would not buy a LP tank for my needs around here unless I got a great deal on one. I will stick with HP, but LP work better for some people...
With all that said I think that a HP 100 is a sweet tank.
Oh and I prefer Worthington tanks because of the Hot Dip Galvanized finish, which has also been mentioned by Rainer too. Great finish on the tanks. If I got a killer deal on some Faber (painted) tanks I would not pass them up espically because I dive fresh water, but I really like the worthington finish and buoyancy characteristics of worthington too. Some of the Fabers get positive when they are empty, which for the mainly cold water diving that I do would not be great for me...
