here are a small portion of the threads devoted to your question. it comes up weekly.
there are no REAL safes in that price range. But, Liberty, Cannon, Browing, etc. are all the same basically, just find the one that has the features you want at the price you can accept. Allways buy bigger than you need. I have a Liberty. here is a link. basically i think its crap. and too small. anyone one of the residential security containers, a guy could break into in couple minutes with an ax or pry bar. they really are a joke.
