Looks like Cap is 250# on their 1" bar

Bars don't typically snap, they bend.
yes im pretty sure it's not a olympic bar. it looks like this http://www.amazon.com/CAP-Barbell-Standard-Threaded-Collars/dp/B002OOYLGO
Grip is awkward on the Ez bar, it'd be difficult to go heavier with that(you can't load ez bar much either).
I have bought a bar myself, and because olympic bars are so expensive, I bought something like This and then slowly bought plates for it to use, which is really awesome, since I can practice deadlift, ohp, squats, etc. at home and do them throughout the day, like grease-the-groove type training. If you have plates with 1in holes, you should buy that one.
While I was looking for it, I saw This bar too, it looks like a great choice, and if this kind of bars were available I would have bought it. If you have 2in plates right now, you should buy this one.
Have fun.
