In a generalised answer, you will need the belt grinder no matter what. Training can come at any time. There are hammer-ins that cost $50 or less (some are free). Classes by the ABS and other groups at places like Haywood college ( in NC) are in the $300 range.The Moran school of Bladesmithing is much more expensive, but well worth it.
It may be best to get the grinder, work on your fit and finish as well as grinding skills, and start a savings to go to a school or other training.
