@PeleSpirit 3D printing is fun but it can be a time sink. Consider how much done you can invest in this. If you want to push on with other things then POD may be best. If you want to have it as a tool in your bag, then buy one for sure.
One thing I would say about resin printers is they can't be left for long periods and are best cleaned and packed away if you aren't using them.
@KroninJ @joemansmoke oh and a set of files can be useful as well.

Useful for the small supports and difficult to reach ones.
@eggspresso most infrared (IR) thermometers have a way to adjust the emissivity. Emissivity is basically how well the object gives off IR. As you suggested black electrical insulating tape is good. If it it thin tape then put two layers down. The emissivity of this is 95% which can be input into the thermometer.
@parallax I can vouch for the Mars 3. To some extent it depends on what you are printing but 28mm miniatures are great.
