It depends.  Quite a few DoS attacks are not based on bandwidth
saturation or network device overload.  On the other hand, if you
address the easy ones within your own network, the attackers might
switch to types which you can't deal with on your own. 8-(

Anyway, you should examine *why* you (or your customers) are attacked,
and address that.  Everything else is likely cost-effective.  Of
course, this might mean you have to do without some revenue if you
have customers that are DoS magnets for some reason.
