Gray ... I don't mind trading insults with you, but sharing knowledge - is a much better route, in my estimation!!!! ...
The beginner cameras I itemized - were the Canon EOS Rebel T7 (NOT T7i) D3400/D3500 (now) Pentax K-70 and the Canon EOS Rebel SL2 ...
The T7i and the EOS 77D are - essentially the same camera ... but the latter includes the top-deck LCD of the EOS XX series. No idea why the price is different for the two models ... when Canon introduced the two of them together (as they had the T6i / T6s before them) the EOS 77D was seen to be the EOS T6s upgrade ... but, after Canon saw the sales not to be as good for the 77D as they were for the T7i - they reduced the price on the 77D ...
By contrast - the T7 (no "i") is the upgrade to the T6, which was the upgrade to the T5, which was the upgrade to the T3 (which you and I have) ... shown in my icon, and yes - the T3 was also MY first DSLR ... and am still wowed by it, whenever I shoot with it ... an excellent camera!!!!
Unfortunately - the Rebel beginner series, lacks the Self-Clean sensor, and has no flip back LCD, either, nor do they incorporate a Touch-Screen.
The SL series DOES incorporate a touch-screen, and the latest SL2, also has the flip back LCD of the "i" series, too. But, it's still a beginner camera.
Because of these features - I included it in these "beginner camera" choices. Truth be known, the SL2 is more aimed at those needing a smaller, and less obtrusive camera, to use on the street - so, it has many of the niceties of the "i" series. But, because of the slightly lower price, I included it, here.
As shown in my signature, my Canons include not only the T3, but also the T4i (which was the very first DSLR with a Touch-Screen) and the EOS 60D - bought at just about the same time. EOS glass I've purchased since, include the EF-S 15-85 IS USM, the EF-S 18-55 IS II (came with the T4i) and various 3rd party items, including the Tamron SP 60 f2 Macro (a fave) the Tamron SP 70-300 VC USD (another fave) the Tamron 18-270 VC PZD (kept on the T3) and the Sigma EX 10-20 USM, and Sigma 70-300 Macro, and the Tokina 16.5-135 (kept on the 60D) ... recently sold - Tokina 80-400, Tamron SP 10-24.
Nikon glass include ... you don't really want me to go there, do you? ... I think you're more interested in Canon ... same with Sony, and Pentax ....
Yes, I lived in London - both as a child with my parents for a while (in Middlesex) and again when I returned there as a youth in the mid-60s (Earl's Court - pretty much - downtown London) - for just short of five years, but I returned to the US in 1972, and have been here (mostly, in CT) - ever since ....
