Disclaimer here: I don't have experience with that vest, so what I say below may not apply... but generally it does.
$100 is a pretty low budget for a vest. You can get one for it, but it isn't likely to be of good quality. Cheaper vests tend to rip, break, snag, fray, etc.
For a budget of $100, you might be able to find something of good quality in the ASC classifieds. There are usually good deals on good quality gear there.
In order to access them you have to be age verified, you can read up on that process here: http://www.airsoftcanada.com/showthread.php?t=49408
Edit: Actually, I'm not sure if you need to be AV'd to access the equipment classifieds.
