It is, however, perfectly legal to use a radio designed for
the public service frequencies to transmit on the ham bands.
Many of the commercial radios can be programmed to transmit
and receive in the 2m band. If you want a single radio
solution, this is the way to go.

You still have the antenna issue though.  As was mentioned,
many antennas are advertised as operating over 130 - 170
MHz, but that means they can be tuned to any frequency
in that range, and will only have a low SWR over a few
MHz around the frequency they are tuned to.  When looking
at antenna specifications you are interested in the "SWR
bandwidth" specification.

There are some antennas designed to operate over a very
wide bandwidth - here is one example:

This is basically a wide-band quarter wave antenna, and
I'm sure there are other similar options.  But this antenna
combined with a commercial-grade radio that will also
transmit on 2m will probably give you the most flexible
single-radio solution.
