For small parts that fit inside 180 mm, the A1 mini ($199 on sale, $219 typical) is the safest buy because it pairs a 30-day return window with a 2-year warranty. Pay $60 more for the A1 ($259 on sale) only if you will print parts wider than about 180 mm. The Ender-3 V3 SE ($179) gives about twice the A1 mini’s volume for $20 less, but with a 14-day return window, an up to 12-month warranty and a 260 °C nozzle limit.
The Ender-3 V3 SE is a reasonable budget buy at its $179 listing if you will print PLA, PETG or TPU 95A and want more than 180 mm of plate. Skip it if you need ABS or ASA (its nozzle tops out at 260 °C), if a 14-day return window is too short for you to learn a first printer, or if a planned basket of upgrades would push the total past a Bambu A1 mini at $199.
If you will print PLA, PETG or TPU, buy an open printer; Bambu’s own A1 mini page says those are the materials that do not need an enclosure. Pay for an enclosed model when ABS, ASA, nylon or carbon-fibre filament is a real plan. On Bambu’s US store the enclosed P1S costs $90 more than the open A1 on sale ($349 versus $259) for the same 256 mm build volume.
