I'd go for the monitor you are more interested in, or is more suited to what you want to do.
Don't let soldering be a determining factor. You could bypass the soldering by using butt connectors if you really wanted to, and/or if you don't solder at the monitor you'll probably end up soldering somewhere else.
Like
peecee said, soldering is something you can get the hang of with a little (and I mean little) practice. It's not critical that you get a NASA certified (tm) solder joint, as soldering if generally forgiving. (Yes, NASA has like a 100page technical document on soldering).
Do a google search for "how to solder" and you'll find some good tutorials, as well as this video is excellent:

Besides, once you get a soldering iron you'll no doubt find more things that you need to "fix" around the house =)
