I'm looking for a simple, accurate and preferably low cost inductive probe that can plug into a RAMPS board. Does anybody have a good experience to relate? I'm hoping it won't require any extra electronics and be able to work mounted a 1mm or 2mm higher than the nozzle. It would be really nice if I could just order it off of eBay. It would be helpful if you can quote your M48 repeat-ability numbers too!

Any suggestions and comments are welcome!

Thanks!
