You literally gave us no information other than the ram amount you wanted, and some BS about analysis, reviews, and testing... How are we supposed to recommend you a laptop/mini pc when all you give us is the amount of ram you want and refuse to tell us what the computer will be used for, your budget (I see now that you have finally told us a dollar amount), and country? You're acting like we're dumb for not recommending you anything, but you won't answer any of the simple questions we need to know to recommend you a laptop/mini pc.
And again with the most vague request ever, just the ram amount, and good in the basic ways of any good laptop? You've gotta be joking.
You're budget is $200 to $300? You're not going to get anything new that's for sure(unless you went for a Chromebook), go for a refurbished HP Elitebook and just be done with it. You still haven't said what you need it for or where you live so who knows if it will work for your uses or if it's available where you live, but with your budget I don't think you'll find anything better.
