Best lnb for general use. I do not need one to pick up signals from the New Horizons space craft, leave that to Analoguesat, gets better reception in all the the rain up there.
I know you orderd an LNB now, but out of curiosity:
Can you be more specific about your criteria for "general use"?
If it is watching normal TV within normal footprint for 5 years on a reasonably sized dish; then just about any (non-counterfeit) LNB these days will do the job.
The IBUs and the Invacoms etc are fine - but probably overkill for this application.
There are many Opticums, Titaniums etc that work almost as well.
On the other hand, if you mean "general fringe-reception DX'ing use on polar-mounted dish", then yes certainly the IBUs are good allrounders.
Unless you need something that attaches to a feed-horn... then most people say "invacom", although I think the Invertos C120s work well too.
As for the budget LNBs - some of them are actually surprisingly good.
I have just tried a no-name (well, "Maximum", but they certainly didnct design and manufacture it) 4 EUR LNB on fringe reception for 28.2, and got only slightly worse results than the IBUQ, and better than several other "high-end" LNBs.
Now, all of this is out-of-box, and certainly not considering criteria such as life-time (cheap stuff don't last long), consistency of performance across the lifetime, water and moisture resistance etc.
What would you consider to be criteria for "general use"?
