I haven’t used the flashforge but my brother who never did any 3d printing before got it and loves it. He says it just works. I just got the elagoo centauri carbon for 300 and it’s so great but might be out of your price range. If your just printing with pla flashforge is probably the way to go. I never liked bedslingers since tall prints tend to tip over or delaminate and I keep my printers in my garage where temperatures can swim and change the prints drastically.
