Shop Bought Power Supplies

If they are all 24V AC, you could use a single 240V -> 24V AC transformer rated for at least 60VA.
Altronics sell an 80VA 12V + 12V unit (connect in series for 24V) for just over $40.
Jaycar sell a 160VA 12V + 12V unit for about $55.
You'll also need an enclosure, power cord and mains fuse holder + fuse.

Have not seen such a tutorial but it would be a simple task. Just connect the 2 wires to the new power supply instead of the old plugpack.
Using a central power supply is a first step toward computer control although I'd recommend a DC power supply for that purpose and this is not always as simple to set up. AC is the way to go if your intention is to keep those lights static.

If you don't want to do the DIY, you could get some of these:

I have spare plugpacks that came from incandescent light sets. These should be powerful enough to run multiple LED light sets. Happy to post them to you because they're worth $0 to me.
Let me know if interested and I'll investigate how many I have and what power (wattage). Not sure how many of them are 24V off the top of my head.

Be very careful trying to parallel the outputs of multiple transformers. You may end up burning them out if not done correctly.
Also, if one becomes unplugged from 240V, it's mains plug pins will become "live" due to the other one pushing it. Not nice at all.
Unless you know exactly what you are doing, try for a single transformer solution.
Well spotted David_AVD.
I was suggesting using a single plugpack from an incandescent light set to run multiple LED light sets. Don't wire multiple plugpacks together.
Not sure how much it'll matter to you but those old heavy plugpacks are not as energy efficient as the newer ones.

New lightweight (switchmode) power supplies won't actually be a 50Hz sine AC output, so won't work with MFCs that are designed for iron core transformers.
The 24V AC 3 Amp (72VA) one linked a few posts above is probably the safest and easiest way to do it.
