Hehehe! That my friend is the bitter- sweet taste of it. Kind of you love me seek me.
I share your very concern coz I have 180cm with gulf star cband lnb and my experience is just the same.
However! I did my homework but its kinder of like still in the proposal stage. The reason for that is I made up my mind to invest first in an lnb before I go for the Big ugly dish of 8 feet, well! At least for our East African standard though(who made it a standard anyway?) So I thought if I could get top of the line c band lnb ( in terms of a hunter for the weak signal ) I would test it with my 180 cm first before I dig in to 240 cm.
Another reason is I believe in squeezing on what I have to its last drop.
So I made a literature review and this is what I found people calling the best!
TITANIUM C1-PLL.
As the title suggests, its made by the Titanium Satellites.
Go here for their website.

And here for the review
OFFICIAL TITANIUM C1-PLL REVIEW
Like I said its still in literature review, for the reason that I ordered it and its on its way from USA and presumably by Friday next week it might be here.
This Lnb you can only buy it from AMAZON or EBay, its not available in Alibaba or Aliexpress. Infact buying from themselves its prefereble as you are sure of the quality.
Pricewise its 38 usd if you buy from theirweb where you get the lnb itself with a prime focus scalar ring. If your dish is an offset, you have to add 18 USD on top of it for an offset scallr ring .
For shipping they charge 23.25 to TZ ( Based on my location. For your location it might be different) making it 62.5 Usd
But I ordered it from their EBay account for the total of 60.57 USD including shipping.
Once I get it, I'll report back for the fact that it might be a different story, by the way someone has to take the risk first. However, based on my google research I have this belief that this is it. Let's pray that the slogan that says you get what you paid for works.[emoji2]
At least for me this is what I have to say, sorry that its a bit messy.
I submitt.
