Option on a 3D Printer on a $500 budget

[Shankman]

I second the nomination for the Two Trees Sapphire Pro. Here is what I did to modify it to get some really nice ABS printswith all of these additions I'm about $ 450.00 in.Changed out the hot end to a E3D V6 all metal changed out the firmware to MarlinAdded BL Touch sensorAdded glass plate to compensated for the concave aluminum plateAdded corrugated plastic sheeting to all sidesI drilled a hole in the top left hand corner to route the cables through.this helps to get a good seal on the back coverWhat needs to be done but there is no hurrychange out the noisy power supply fan
