You will want to go with a removable mount, so you can take it off when you don't need it (also cuts down on theft potential). I used a sliding mount that allows me to move the motor back 6" or so when I don't need it (keeps it out of the way from bumps and makes the bow clear).
I like the MotorGuide mount better than the MinnKota because of the ability to slide the motor back and forth. However, as you might expect, the bolt patterns are different, so you will have to drill new holes if you want to use a MotorGuide mount with a MinnKota motor. One advantage of MinnKota's mount is that it is available in white, whereas the MotorGuide is not - I had to paint mine to match my boat. Check it out and see what you think:

That really rules out the MotorGuide motors, as they get very heavy with that big stainless steel shaft. MinnKota has a composite shaft that is lighter and flexes rather than bending. I went with a MinnKota Riptide 70 PowerDrive Autopilot, with the cordless remote. The remote allows you to operate the motor from anywhere on the boat using a little key fob remote. I also have used it to move the boat away from a dock when I stepped off, then move the boat back to the dock when I was ready to get back on the boat. Robo-boat!
If you are going to use the motor in salt water, make sure the motor is designed for salt use. MinnKota motors for salt water are called Riptides; MotorGuides are called Great Whites. Bass Pro Shops has a nice selection:

Also, you will need #4 or #6 wiring from the battery (or batteries for 24 or 36 volt motors) to the trolling motor.
I will try to post some pictures of the mount and setup, but now it's time to see if I can catch some fish! You can see the overall boat with the motor on the bow at:
