There are talks on Reddit about which to buy, a delta printer or a prusa i3. Both of the 3d printers are RepRap origin suitable for personal 3der or maker.
What advantages and disadvantages are there to a delta printer vs something like a prusa?
Advantages to a delta printer:
large build area (especially vertically)
ease of scaling the design vertically (just lengthen some rods/extrusions)
simpler design, since all three motion axes on a delta are identical and lightweight, whereas one axis must ride on another on a Cartesian bot (e.g. the x axis rides on the z axis on a prusa)
Speed is a big plus on delta bot. Delta printers are ridiculously fast in comparison to Cartesian bots which is important with large build areas.
Disadvantages:
More complicated calibration procedure
Can produce moire artifacts on some shapes (maybe fixable?)
Requires a bowden extruder to reduce weight and to print, using a bowden extruder, you probably won't be able to use ninjaflex
The substantial external size of a Delta bot in comparison to a Cartesian. Deltas push the boundary of what would be considered "benchtop or desktop 3d printing" due to their necessarily large dimensions, especially in Z where they require a great deal of extra space above the actual print volume.
The prusa's have a uniform resolution. The Deltas have higher resolution in the center and declines going out from there.

Build one! There is no reason if you have the motivation and patience that you should not build a delta printer.
Steer away from acrylic frames because they can warp from the heat and break much easier. Also auto bed leveling is something that can be added to most printers very easily at the cost of a servo and a sensor.
RobotDigg 2020, 2040 and 3030 Aluminum Vertex provide builders a firm and stability frame for Kossel Mini, XL or XXL.
