Now the question : is there a way to buy an older and cheaper legit device ? ( I do not give a * for analog signals)
Anyhow, 500 euros for Logic 8, well ... come on ...
Even if you're going to eventually get something more expensive, I'd judge the Chinese CY7C68013A-based device to be legit when used with sigrok software.

You can get a Digital Discovery for less and it's far more powerful:

1D50:608C: fx2lafw-sigrok-fx2-8ch.fw (8ch 24MHz)
EEPROM: C0 50 1D 8C 60 00 1B 00 (Rest FF)
1D50:608D: fx2lafw-sigrok-fx2-16ch.fw (16ch 12MHz)
EEPROM: C0 50 1D 8D 60 00 1B 00 (Rest FF)
Details:OpenTechLab on youtube has several videos discussing inexpensive logic analyzers and how to use them with the open source sigrok pulseview software. He also talks a bit about the ethics of using Saleae clones - he was a contributor. It boils down to if the logic analyzer is using open source (non-saleae) firmware and software, then it’s “clean”. It’s just a cypress chip using open source software.
trigger on byte sequence coming from async serial decoding
Which applications support it ?

trigger on byte sequence coming from async serial decoding
USB analysers in the price range you are looking at do not support triggering on uart decode, or any kind of decode. You get edge/level triggers and combinations of those across channels at best.
A possible low cost solution is to make your own trigger circuit.
Program a small mcu with uart to toggle a pin when your desired character is seen, then use that pin as a trigger in your chosen LA.
If the system you are debugging has an mcu, which you're programming, then use that mcu.
Anyway, every low cost solution supports async serial decoding under Sigrok / Pulseview
i cannot show the oriental clone & Saleae SW with my customers.
i cannot show the oriental clone & Saleae SW with my customers.Just use sigrok
Clones don't have Saleae anywhere, neither they include any pirated firmware, the fw is loaded by the program running on the PC, you would only be breaking the license if you used Saleae SW with it.
Otherwise, Saleae design is just the EZ-USB FX2LP reference board with a TTL buffer.
No way of calling it "pirated design".
Not to debate Saleae prices, but they do have steep discounts available:

Disclosure… I own a Logic Pro 16, purchased at 50% discount when list price was $995. I’m a happy customer!
Some years ago i was going to buy a basic SALEAE LA to sniff serial buses with custom protocols (that i develop) but things went in a different way and i used different tools, mainly MCUs programmed for the purpose.
Some days ago, after seeing a friend using an old Logic device with the Logic 2 i finally decided to proceed with the purchase except that i soon discovered that prices skyrocket to the sky, probably i lived under a rock but ... WT* happened in the mean time ?
My memories were about something around 150 USD for the simpler tool, now we start from 500 Euros with the cheapest one ... i fear i do not understand their business model.

My memories were about something around 150 USD for the simpler tool, now we start from 500 Euros with the cheapest one ... i fear i do not understand their business model.I've seen other tools going up in price as well. Most likely it is due to component shortage and needing to buy parts at 10 times the price. About 2 years ago I paid around 200 euro for a Prologix ethernet GPIB interface. Right now they cost around 600 euro. I triple checked: it is the same model I bought!
At the current Salea prices levels it makes more sense to buy an oscilloscope with digital inputs (or upgrade your existing DSO if possible).
The”Enthusiast” discount is not shown for the Logic Pro 8 or Logic Pro 16. I stated I was an Enthusiast and asked by email and was offered 50% off. I think this percentage applies to all models?
