I've never saw this device before.....or being mentioned it here in the forum...

Does anyone use this device and is it still of use nowadays?

I haven't used one but I did consider getting one. It's essentially a PC based AWG running DOS. When it came out (around 1992 if I remember right) it was one of the most advanced AWGs of that time.

Even today it's still a very nice AWG, and LW420s in good condition still go for some noticable money on ebay. Some people also replaced the CRT with an LCD.

Right...I just lately someone replace the CRT with a LCD or TFT....oddly the display showed suddenly different colors (o;

So what would be a reasonable price for it?

Just would be a nice fit to my 9354AL (o;
And I hope it was also made in Switzerland ;-)

I used to have one but sold it a long time ago. Unless you have very specific needs for arbitrary waveforms it is just big and noisy. The build quality isn't stellar either. I'm much happier with my Siglent SDG1000 series generator. The pattern generation part of the LW420 is also not very interesting. It doesn't have a digital waveform editor besides just entering 1 and 0. That becomes tedious quickly.

Difficult question. For once, The WaveStation LW420 is a really nice (albeit as ntnico says big and noisy) AWG, with decent specs even by today's standard, and comes with GPIB (which none of the entry level AWGs do). On the other side, it's now close to 25yrs old.

I'd probably pay somewhere around €200 for it if it's in really great condition and comes with the 1MB memory upgrade. However, most LW420s I saw ended up going for a lot more , which in my opinion no longer made it worthwhile.

Can't remember, but it might very well be, as it's from the same time period where LeCroy made scopes there.
