there have to be making them for someone. which manufacture was using them before we came along and went wow these will make great ATV receivers. are they used in sky q boxes for example or one of the many different makes of multi sat receivers.
Finding a STB using those tuners will be of little value as the firmware / software in the box is very unlikely to allow you to set it up to recieve low SR signals and judging by our efforts at removing the muli-pinned tuners from the BATC PCB, it is unlikely you will be successful at recovering the tuners out of any units.

It's got a cute little colour 2" TV screen, web interface all the bells and whistles
Being unable to control myself I popped the lid off
To my surprise it had a Serit tuner in it, similar number to MiniTiouner
Therefore, one place to find them might be modern commercial equipment
Cost somewhere around 1000 Pounds new
I sell sat boxes and that's my first encounter with a Serit (except my new toy that arrived today...thanks Art!)

this Serit NIM has 2 specificity that you will not find
1) the Demodulator chip is an "advanced" version specific to professional receivers
(like Dektec DTA2137C cost >2000£ )
I think that you will never find this chip on standard satellite receivers/ set top boxes, most of advanced features are not useful for standard TV sat receiving.
2) I have asked to Serit to add inside the NIM a LNA that was not included in the original version they were selling.
They told me that at this date, none of their clients have asked for an additional LNA, but as they have this LNA chip in stock, they could do the modification.
This LNA has an AGC so if the signal is too much high, its gain goes down and at the end it acts as an attenuator.
If you see that your LNA gain is less than 3dB or negative (=attenuator), you know that your input signal is too high.
So, Just to observe the LNA gain to know what could be bad on this side.
(Near the LNA gain, I have added an emoticon in the version 0.9 to give more advertising about the Input signal when it is too high)
This LNA chip is used by ST Micro in their Professional Demo PCB.
