I have seen a few posts in /r/arduino that seem to indicate that it is a good brand to buy from if you are on a tight budget like me.I am looking at buying a few of each of these (for spares and maybe to make a DIY 3d printer at some point):
US $1.75 Stepper motor Driver DRV8825 http://www.aliexpress.com/item/Stepper-motor-Driver-DRV8825-for-3D-printers/32712012629.html.
US $3.75 RAMPS 1.4 http://www.aliexpress.com/item/RAMPS-1-4-Mega-Shield-For-3D-printer-RepRap-Prusa-Mendel-Assembled/32713303343.html
US $5.79 Mega 2560 R3 *3rd link not allowed
What do you guys think?
