I am looking at a couple of different units I can replace my old unit with.

I am looking at the 421, 431 & 441
and the 421s, 431s, & 441s

What is the difference?
They all have the same size screen, resolution.

And pricing is all over the place.
I only really use it a couple of times a year but it would be nice to have one where I could plug in where I would like to go and have it chart it for me. Is this how they work?
 
The 400 series are basically the same unit, the s indicates the unit has sonar(fish finder). The different numbers represent the mapping that is included in the unit, go to the garmin web site and determine which mapping you want/need. You can generate routes on the marine gps however the process is not automatic like in a car. You might try utube to see if there is a video on creating a route on a marine unit.
 
You really should look at moving up just a bit to the Garmin 545s. I have one in our 22' bay boat. My boys really like it and it keeps them off the shoals.

I agree with Bill. I have a 546s and the display is orders of magnitude better than the 400 series. I had bad experiences with 545s and went through two of them before trading accepting a free upgrade to the 546s, which I like a lot.
 
The only problem is I am cheap! :)

And I am trying to not put a bunch of money into something that most likely will convey if I sell the boat this year.
 
You can remove the 545 plotter if you sell the boat. It has a built in antenna.

That is what I really like about Garmin when you have a problem and I have only had one with a GMR24HD radar they eventually gave me a new unit. I haven't had a problem with the 545s in the smaller boat. In fact I haven't had a bad plotter ever with Garmin. I agree the display resolution is fantastic on the 540 series plotters.
