What is this worth?
If it seems to work but needs upgrades?
Here in europe, they seems to be for sale couple of hundreds Euro.
For example, https://www.osta.ee/en/tektronix-tla7012-logic-analyzer-vajab-uuendust-tarkvarale-160049504.html (https://www.osta.ee/en/tektronix-tla7012-logic-analyzer-vajab-uuendust-tarkvarale-160049504.html)
but as I have seen then the prices of the hardware sold are usually below 500. The cables alone should be worth more if I am correct?

The cables aren't worth much either. These are great logic analysers but nobody uses a logic analyser nowadays so you can pick them up for peanuts. I'd like a TLA7012 myself but realistically my TLA715 doesn't see enough use to justify the costs. If you can get it for a couple of hundred euro and need a logic analyser then it is a great deal.
Upon closer inspection it looks like the probes that come with it are not for the module fitted in the logic analyser so basically it comes without probes.

Thanks. Nor do I have any use or very little for it, I mean more than a collectible object - a disease problem that many are likely to suffer from :-DD

After contacting the seller, it turned out that he had more measuring instruments, so I gave up the option of buying this analyzer and will probably focus a Tek TDS6154C - 15GHz scope.
Sadly that this seems broken and previous owner labelled this like "expensive to repair" - i quess input or ADC...but anyway, may be good to own as an exhibit.
This TLA7012 analyzer ended up little over 1k€.

You've got a point, but I don't entirely agree with you: If you've validating DDR3 timing in your design, you will need a good logic analyzer, preferably with the ability to monitor analog wave-forms on selected channels too. But gone are the days of debugging software by having a logic analyzer monitor the CPU's address/data-bus, disassembling captured data and inlining your source into it. (with all the complications that pipelines and cache bring along).
I own a very complete TLA7012, with a number of digital modules, an analog oscilloscope module, the PCI analyzer module and the Pattern Generator module with both differential and single-ended probes. On a trolley, of course. But you're right; It's not worth much. If you need one, there's no other tool that can do the job, but that doesn't happen very often, and the rest of the time it's standing in the way.
I wish it supported more serial protocols: I2C, SPI, etc. But with cheap alternatives getting cheaper and better, it's of not much use. It does decode and even encode CSI, but even that is a dying protocol nowadays. It's a fun instrument to play with tough. For a couple of days.
