PCmag review https://www.pcmag.com/reviews/anycubic-kobra-2

The newest models that manufacturers are issuing have automated most needed user chores so one can start printing right out of the box (some assembly required).  Don't go for the cheapest as it will end up in a corner.

For modeling in O scale, which is a better choice, FDM or Resin? Which makes a stronger part? I plan on making replacement parts like domes, feedwater heaters, steam dynamos, pilots. From reading articles and printer reviews I get the sense that resin printing is more complex because of drying, washing, and the dangerous chemicals. Please provide insight.

For small detail parts resin has better resolution resulting in smoother and more detailed parts, it is also stronger to some extent. For large parts the resin printers print area is just too small, you have to break the model up into smaller sections and glue them together. I can fit a 36 ft scale boxcar on my FDM printer without breaking it up for example. If you do a lot of both small and large projects you should probably have both types of printers.

It is not strength but detail needed for what you're planning.  The hobbyist resin printers have 10 t0 20 times finer detail that FDM printers.  The difference really shows up on curved surfaces.  There are plenty of reviews, both written and video, on the web/

Yes, all resins are more dangerous than filament, but some filaments do produce noxious vapors. You'll need to work with gloves and eye protection, and in a well ventilated area when using resin.  A wash and curing station can ease post processing of resin prints.  If you want a really smooth finish with FDM prints then sanding and filling will be required (a lot).

Search for posts by Forum member Sarah for some examples.

Both technologies have their place in this hobby.

Your biggest challenge will be producing the models you want to print.
