i bought mine from aliexpress prusa i3 kit , or you can follow the BOM and source parts and vitamins locally. For acrylic frame, it will give some problem but dont know when it will happend   it like time bomb   i think i want to convert my i3 to wilson ts for rigidity cause i saw my acrylic frame got a little bend on parts that hold the y axis. if you type of person that love to modified and tweaking thing find kit that come with controller that we can modified and upload the firmware to the controller, usually aliexpress kit that come with melzi board we can't upload or modified the firmware
