Max Record Length: 20K is a bit low these days.

How problematic is the max record length?

It is stay away from it problematic.
It is horrible deal.
For the specs that scope should cost 100-150 USD.

I keep seeing that for this price (~200 USD), you can get better scopes? Where can I find these? I'm in Australia, if that helps, and this is the best value scope I've been able to find so far with 4 channels?

This Vevor doesn't do protocol decoding, right?
Why do you even think you need four channels?
With a tight budget, there aren't many options.

So my reason for wanting to work with I2C is for a single project, I don't need a protocol analyser on the scope, just want to be able to see the waveforms.
I'm well aware that logic analysers exist (and are much cheaper), but I'm looking for a scope because I want to buy a scope, not just for I2C, that's just a single project that I'm doing right now which is just my incentive for finally investing in a scope.
I would like 4 channels because I don't want to be in a situation where I want to probe more than 2 waveforms at once. I don't immediately need 4 channels for anything specific I have in mind, just think it would be good to have.

If the price is right then a used SDS1104XE in good condition would still be worth serious consideration particularly for somebody on a budget. If the OP is not in a desperate rush for a scope then this would be my recommendation, cheaper than new and far superior to what they are currently considering.

I don't know what the market looks like in Australia, but I have been watching various sites here in the US in hopes of finding a deal on a used Siglent SDS1104XE or Rigol1054DZ. So far, the only things I'm finding are people offering them, used, for prices HIGHER than what I can get them brand new from Amazon. :(
