Several years ago when I bought a package from him, I opted for the SNH.
The QPH still costs double.
But, as mentioned, advantages include ability to log circular FTA channels, though there are few.
NASA and Angel One come to mind. Used to have a soccer channel, but that's gone.
Those are on Dish Network. You won't find anything on DirecTV channels.
Frankly, I'd recommend a dedicated little 20" surplus dish if you want NASA.
But, to each his own.
To my mind, the more valuable feature of the QPH, is that it has two outputs for each side (linear and circular)
So, if you need to run multiple receivers, you follow up the LNB with a multiswitch, and you're all set.
Discussion of how to do that is well documented over in our FAQ department.
Of course, that requires both receivers look at the same satellite, so that is less desirable...
Folks with two or more receivers often have multiple dishes, all shared .
That way, either user can select whatever he wants.
And other than the price, the only negative I've seen about the QPH, is that it's quite heavy.
Some folks seem to worry about it causing problems, while others don't report any.
I won't recommend either way.
I have an SNH, and many other LNBs (both linear and circular; some quite cheap), and am very happy.
edit: oh, the SNH is Universal with two Local Oscillator frequency; the QPH is Standard with just one.
If you need to see a satellite in the low band, that could be a deciding factor (but probably not)
