To add to the above.

 

There are a lot of varibles that you will have to consider.

Warranty, some have no warranty at all, I know that sounds strange but thats the way it is.

Maximum size of print or volume, which varies a lot.

Print speed, doesn't really matter unless it is used all the time.

Number of print heads or spools it can switch from.

Print media type, there are a lot of them. The prices vary drastically from one material to the next.

Is the print head part of the cartridge, spool fed, metal or plastic etc. Basically longevity and ease of service.

Cost per print (which varies drasticaly between some models) Spool fed are the cheapest per print depending on what type of material your using.

This is supposedly one of the best ones for personal use. It is not the fastest, and is one of the highest costs per print.

The other end of the spectrum would be a simple spool fed one like this.

Spool fed ones can print far more types of materials than cartridge ones. They are far more versitle, easier to service, and a better buy in my opinion.
