No offense - but if $5K is an issue for your employer, after a year of essential magic, you might have the wrong employer and they might have the wrong employee...
I was lucky in that my first job was at a small non-software company that forked over huge amounts of cash for Oracle because it literally enabled their business to succeed (mysql and postgresql were nowhere close to being able to do it at the time). And yet I've seen fellow developers waffle over spending $60 on something they will use literally every day.
