Welcome to the Quilting Board!
I NEVER have to thread my serger's bottom loopers - the ones that everyone hates to thread, and I have had it for more than 20 years. When I want to change colors, I cut the looper thread about two inches above the tension disks. This is just below the thread guides. Take off the old thread cones and add the new ones. Put the thread through the guides until you come to the cut end that is still in the machine. TIE THESE ENDS TOGETHER SECURELY.
For the top threads, I remove the spool and pull out all the thread. The top threads are very easy to get through the needle and put under the foot.
Then just sew until your new looper thread is coming out under the foot.
Well, once in a while the knots come loose, and I have to rethread the bottom, too, but a few times in a few years doesn't bother me.

I have an Elna that I bought over twenty years ago. I don't use it a lot, but I'm glad I have a serger. Yes, it has given my fits from time to time. I'm so happy when the tension is right and it sews beautifully. I didn't know they now make sergers that are self-threading. If I used mine more, I'd seriously think about upgrading.
If you can afford the self-threading ones, get one of those because machines of that quality are going to be quieter and nicer to work with.
I have the Brother 1034D and it's been working great for about 3 years. VERY easy to thread - next best thing to self-threading. Switching to narrow rolled hem or back to normal serging takes about 10 seconds.
But it *is* noisy. I just live with it because I love it so much. But, when it breaks, I'll look at the air-threading sergers and see if I can afford one of those. If not, I'd definitely buy this model again.

I have a Babylock, one of first sold back in early 80's, a three thread and it is a wonderful machine, although threading can be a pain, it is not that bad. Looked at the new self threading baby lock and could not justify the cost when I had the baby lock. Go check them out and then check Overstock.com and see if they have it on there and how much they want. I got a brother sewing machine for $131. including shipping and Wal Mart wanted $199 for same machine. Also, maybe a used one that someone is selling. Here in FL they come up for sale when someone passes on and you can get great buys on almost new machines.
I have had 3 sergers. The last 2 (which I still have) are Babylocks. The jet-air threading is a life saver. The first serger I bought (another brand) Had a wonderful stitch, but I spent more time threading it that sewing with it. The Babylock sergers are so much easier to use and so much more versatile.
Make sure it's self threading, whatever it is. I also like the differential feed on my Janome. I can put ruffles on things in one swipe!
