I am an electronics engineer and do my own board layouts with Altium - - - a bit more than an open source or free tools. but the cost is worth it for the power and performance and the libraries
The cost in dollars perhaps, but also the cost in lack of freedom? When doing Open Source / community work I answer the latter question differently than when being employee.
Anyways, here's another mailing list post, explaining this RAMPS replacement mystery: [reprap.org] It looks like in practice, people don't burn their Arduino, but rarther their RAMPS, and replacing just the RAMPS does not require uploading new firmware and such stuff.
