I have some experience 3D modeling and am very tech savvy with computers. So I am looking into a buying a printer from a brand that has great customer service. I have no knowledge on this market, nor the parts that make up the printer. I've been making prototypes, however it becomes irritating when you have to wait a while to get the part. The time has come to actually get one so I don't have to wait. PLA and ABS are the only materials I use. Is it true that a heated bed and sturdy metal frame is worth having?

Budget: $150 - $250


Any info is appreciated!
