I need a battery back up for my comp. If it gets even a little windy here, our power goes out.

Which one do you suggest? Shoudn't be more then $150

I am really thinking bout getting this one:



And how would i set it up? Would i plug the back up right into the wall socket then plug my surge protector into the back up??? Or would i just plug all my stuff straight into the backup? Or would i plug the back up into the surge protector??
