Hi Roger,
Thanks very much for the reply. I did forget to mention that I will be using my Kenwood TS2000 for this purpose. This allows me the full 0-100 watts choice for 2m, and 0-50 watts choice for 70cm. The preamps are only for receive. The RF switches are between the rig and the preamps and will bypass the preamps upon transmit. I can start out my RF out anywhere within the above stated ranges.
Any further thoughts?

The answer is actually in what transmitters or power amplifiers are you planning to use that fit within your budget?
Watts cost money...
With a limited gain omnidirectional you might best aim toward the middle range but if you are looking at used SSB/CW equipment at 430, many of the less expensive older radios only ran 10 watts out. Of course a "Linear Amplifier" for SSB/CW could move you up but is not necessarily inexpensive.
You might want to just accept the fact that you may need to "climb the tower" again once you settle on your transmitters.
