Use DHCP, get your customers to use DHCP.  Current Best Current Pratices
for IP allocations (http://ftp.fc.net/rfc/rfc2050.txt) states:
   5.  Due to the requirement to increase the utilization efficiency
       of IPv4 address space, all assignments are made with the
       assumption that sites make use of variable length subnet mask
       (VLSM) and classless technologies within their network.  Any
       request for address space based on the use of classfull
       assumptions will require a detailed justification.  The use of
       classfull technologies for the purposes of administrative
       convenience is generally insupportable due to the limited
       availability of free IPv4 address space.
...
  7.
       While it is understood that the use of static addressing may
       ease some aspects of administration, the current rate of
       consumption of the remaining unassigned IPv4 address space does
       not permit the assignment of addresses for administrative ease.
       Organizations considering the use of static IP address assignment
       are expected to investigate and implement dynamic assignment
       technologies whenever possible.

This means that you should use renumbering technology as much as
possible, so that when you can justify a /19 you can get one,
until then, find an ISP that is multi-homes and can provide you
the IP addresses you need, and consider two connections to them,
giving you the benefit of being multi-homed without the cost of
the routers needed for full BGP, or needing to justify a /19.
