TDS200 series could be one of the most popular scopes for beginners and hobbyists, there are still lots of used one available and are affordable for beginners, however, the monochrome display with 320x240 display is kind of outdated, an extension module (TDS2CM or TDS2MM) is needed to have RS232/Centronics/GPIB interfaces to send data to PC for better vision/processing
My first scope was a TDS210 with a TDS2MM. It was great, back in 2000.
But today, realistically ? They have abysmal sample memory size (2500 points per channel), lack many features such as protocol decoding, only have an 8 bit ADC, as you mention the LCD is pure crap, and even the FFT sucks. USB communication was slow as hell, I remember screenshots were taking a while and I had to simulate a printer. Their firmware cannot be updated (although I agree, there are little to no bugs - but there are also no features...), and they have their quirks (common issue is a hardware failure of the BNC ports).
I don't want to discourage the effort by any means as I love to read about my first scope and see creative projects, but I really wanted to warn beginners - the going price is around $150-200 these days, apparently.
Even at this price, there are better options like a Hantek DS2C10 ($189, yeah it has some bugs, but so many more features, can be modded, same bandwidth and higher if you mod it, integrated basic AWG for $20 more, USB host for screenshots, it's a new scope and not a 20 years old unit that can start to have its CCFL-backlit display failing ...), and with only a bit more you can get a Rigol DS1054Z or a Siglent which is even one step higher.
I would not advise a beginner to buy a TDS210/TDS220 these days... I would not call it the perfect beginner scope in 2022... Just wanted to share a contrasting opinion.
Now, let's go back to the TDS2CM/MM.
