On the budget LA: Kingst LA1010 vs DSLogic U2basic
VSV_electron:
Hello, for my upcoming legacy 8bit MCU adventures (AT89C51, PIC16F887) I'm thinking of getting a simple but relatively reliable (in overall performance and quality) LA on a budget.
I've narrowed my choice down to these two basic models:
DSLogic U2basic https://aliexpress.com/item/4000386257930.html
Kingst LA1010 https://aliexpress.com/item/32780046572.html
Being completely new to the LA stuff (apart from watching a bunch of reviews on YT and reading some threads here on EEVBlog) I can't go deep into the analysis of their features so please advise which one would be more favorable in terms of overall performance and possibly reliability.
What I noticed is that while the Kingst LA1010 is fully supported on the official Kingst website the DS Logic U2Basic on the other hand is absent from the current models lineup of DSLogic. Are the ones still sold counterfeit or are they rather Old Stock units?
I understand that from the overall performance point of view the DSLogic U2basic is a more desirable device because it has 64Mbit RAM on board while the Kingst LA1010 is RAM-less.
I'm not sure whether that difference alone can steer me towards the DSLogic U2basic instead of Kingst LA1010 though.
Lastly, what I'm losing if I get an 8$ Saleae clone instead of either 60-80$ of the two above? Is ~10x the price difference worth it?
Please advise.

If you must have one, then buy the cheap Saleae clone.
The others are OK, DSLogic is better AFAIK, just that in practice you'll almost never need a LA, you'll see. I have a DSLogic and never use it.

IMO, no. I have DSLogic U2basic and I never use it. There are probably cases when you absolutely want the fastest sampling rate and a lot of channels. But in most cases I much prefer simple continuous capture at a slower sample rate. Dealing with trigger setups is annoying for quick tests.
I would just start with $8 one and get a better unit once you know what you are actually missing. Especially for AT89C51 and PIC16F887 you are not going to need high sample rates.

The question is really whether I must have one? That's a good question indeed. Could you please elaborate on your statement about having the DSLogic and never using it? I've got a decent low end digital scope, the Rigol DS1102Z-E. Would you suggest that adding a cheapo Saleae clone or a slightly more advanced DSLogic LA will not give me any advantage over a 2 channel digital scope?
Actually I've read between the lines in some posts that yes, it won't which is in line with what you say but since so many people buy these lower end LAs and express their happiness about owning and using them there must be something to it?

Thanks, I alrready asked it above but anyway - will a cheapo $8 Saleae clone give me any benefits as compared to my digital Rigol DS1102Z-E scope?
