My husband is currently towards the end of his first year on the Geo Tech course. Definitely talk to the BPSO - there are some rumored changes coming down the pipe that, if true, will significantly change how training is handled for the course, and MAY (no, I am not SURE of this) result in there being no class starting this fall.
The trade is still definitely in need of people, from what he's telling me, but training/courses may be a bit of an issue.
