Seconding this. It's because I've been saving up for the past few years that I have the money to attend the summer batch. I didn't know that I was saving up for hacker school, but I'm glad I was saving :)
I'm finishing up the current winter batch, having started in a position similar to yours. I think you'll find that it's time and money well spent. I've been invited back for this summer's batch and will likely be back. If I am, see you in a month or so :-)
