I need one that is a decent quality nothing fancy but something that isn't going to break on me. I am going to be gaming on it. If the only connection it has is VGA, I just need something to use. It needs to be under 100.
Either search on Newegg, really any 1080p monitor will do you fine. I'm sure you can find atleast a 21" monitor on there for $100. Or go on ebay and try bid for one, you may be able to get a good used monitor for under $100 depending on how the bidding goes!
I'm not sure where you're from or what currency you are using, but here ya go...

I am probably going to go with the second option. Thats for showing me.
