Dump bank limits?

[BuffaloBoy]

For those who dump a lot of coins at dump banks, what is the limit on how much you would dump at one bank per visit?
How many dump banks do you use?
How often do you dump at each dump bank?

granted they have a metal box vs bags so it doesn't take the tellers any effort at all.. i dump here 2x a week.

Can you elaborate on "metal box vs. bags"?

I just got started dumping my first $1000 of halves at TD and it is a total PITA because the bag fills up at $100. The teller basically had to sit with me (I dumped about $400 worth) the whole time and a TON of halves kept popping out the reject tray for no particular reason.
