I have been looking at the Siglent and Rigol options but I only have the budget for the really entry level models which would probably have similar specs

$200 is a bit on the high end.
The Tek is technically 25 years old, afaics. It has a floppy disk!  ;)
I don't know.

The Hantek is okay for ~$150, but for $200+ I'd rather save up for a Siglent/Rigol.
You can get the Hantek cheaper though, right?

Save 

Get Siglent or Rigol,  maybe some xmass lower prices ??  and add some free bw upgrades  loll  new models are out and cost effectives ...

for an oldie like the Tek  you have to be sure it pass self tests and yes  you have the "battery" problem who could happen, and yes it's old 

Hantek, meh  works but cheaaaap     get the 2d15  ???  so far i don't hear about many problems on them ...   you have a thread about them  here

for all machines ... be sure to get the latest fw updates     os some ol floppies  for the Tek  loll  had problems to get some  :palm:

Samples/second is an irrelevant metric: the only metric that matters is bandwidth.

Examples:

* 35 years ago I was using HP scopes to examine 800ps risetimes. It was 25MS/s
* I have a 200ps/1.7GHz 1970 scope that uses BC107 (fT=350GHz) transistors in the signal path
* I have a scope with <100ps risetimes and a 37kS/s sampling rate

I’m tossing up whether I should get an older Tektronix TDS3012B or a newer Hantek DSO2D10 oscilloscope. As the Tektronix is probably built better but the Hantek is more up to date. Which one would you go for?

Provided the scope works, either will be better than no scope. Beyond that we would need to know what you need to use it for.

The cheaper scope would be better if it enables you to buy other necessary equipment.

Don't forget to ensure you have the right class of probe for your use cases. Probes aren't cheap, and the wrong class can ruin your day. FFI, see the references at https://entertaininghacks.wordpress.com/library-2/scope-probe-reference-material/

Example: the Tek IsoVu probes have a base price of £10700. I doubt they are what you need! https://www.tek.com/en/products/oscilloscopes/oscilloscope-probes/isovu-isolated-probes

Would you, please, stop confusing people with useless comments of how sampling scopes sample at slow sample speeds..
They do not. They have equivalent sampling rate defined by sample aperture of individual sample in reconstruction  process. They do not violate Nyquist, but cleverly reconstruct signal shape from thousands of separate trigger events.

And people are talking about Real Time sampling scope for which realtime sampling rate IS important.
You know, like ANY average scope made in the last 20 years...

And in the last more than 10 years, scopes mostly don't even provide ETS function anymore..
