Most people recommend the new 8 or 10 for performance reasons, but I went with the oldest cheapest ones I could find for price. You can find the old 2019 Fire Tablet 7 here under "See All Buying Options, only $18.70 at time of writing". Alternatively here's a listing for the old used Fire Tablet 8. Just know that these tablets are old, slow, and have unacceptably terrible software. They're only really usable if you use Fire Toolbox to remove most of the bloat and even then they're underpowered but can work well as wall panels. I talked about a few of the steps I did to make them more useable here in a different reddit thread. If you do go this route, make sure you do not connect the tablet to the internet before you debloat it using Fire Toolbox and disable auto updates. Otherwise Amazon will patch the exploits used by Fire Toolbox and do things like re-enable lock screen ads or run performance and memory draining services in the background.

Do you know how well it plays SW?

Edit: did some Google Fu and it seems like the Fire 8 HD is a better buy due to the increased RAM which gives it smoother performance. It's only $20 more for the 16 GB model. Link

$30 total for the Fire 7. https://www.amazon.com/dp/B01GEW27DA/ref=cm_sw_r_cp_apa_yVezzb14RTXSN

The Fire 8HD is going for $50 instead of $80 as well. https://www.amazon.com/dp/B01J94SWWU/ref=fs_ods_tab_ds
