Began looking for spares, such as Ramps 1.4, etc. and began at Amazon. Quickly found lots of offerings, including kits with Arduino and LCD and sundry. Most, if not all, have very iffy customer experiences reported. That may or may not mean that much as many technical people cannot be bothered to report, unless really really pleased, or really really NOT pleased. But the fried board comments do give pause. Any reliable sources known? Or simply order several of the cheapies and hope for the best?
