Ask HN: How should I use my $2000 training budget before end of year?

I am an Engineering Manager at a company that offers a $2000 yearly training budget and I did not use any of it this year. It's reset in 2 days. What should I buy with this? The rules are pretty lax as long as it's loosely related to Software Engineering, Management and/or Business.
