I wouldn't go with everlast heavy bags because they tend to have hard spots. I have a 70lb vinyl century I'm happy with. Does the job just fine. The next time I need to buy one I'll buy a Title.

Forget the speedbag for now. In an apt you'll have no place to hang it, plus they're so loud the neighbors will kill you. Plus, you won't be able to get a decent quality bag/platform/brackets for anything under $200. The $50 packages you see in the sports superstores are garbage with zero action. That's why I made my own. Title and ringside make good speedbags. I have a gyro everlast and it's pretty good, but if I knew then what I know now, again, I'd go with Title.
