The largest 'affordable' resin printer (aka under £500) is the Elegoo Saturn which has a build size of 192mm x 120mm x 200mm which is quite an improvement on the older 'Mars' which I've got and is not that far short of a basic Ender 3 or similar FDM printer. Albeit it is 3 times the cost of an Ender 3 and the resin is way more expensive than filament. But if you want that size and resin it does give you something that a couple of years ago would have been unthinkable.
Happily collecting things all my life...
