I would personally rather spend the <$15 to get a ZVS induction heater module prebuilt rather than dealing with a CFL hack. Just throwing that out there in case anyone was interested and didn't know you can easily get cheap modules

Me to, but I love DIY hacks like this, especially ones that repurpose broken items. No way would I would ever really buy a new CFL, but I might consider using an old one, probably after sweeping up some broken glass with toxic mercury vapors, lol.
I'll never forget how easy it is to make one from a CFL and some copper wire at least.
You could probably use a few CFLs together, and make it 4-5 times more powerful too, just like the even more expensive higher wattage modules online..

Other than the module what would you need to get that to work? I am desperately trying to get away from my alcohol lamp.

If you are gonna go through all the trouble, I recommend watching electroBOOM's video on building one. They aren't terribly difficult to make if you have some soldering skill and patience.
All the inductors I've built from scratch actually use this basic free schematic slightly modified, but it works fine as is.

Even if you get a cheap ZVS module from amazon or aliba, the next most important piece is the power supply, which should be 5-12V and deliver at least 10 amps of current. 20 amps is better (quicker heating, less on time, etc)... And this is going to be at least half the overall cost of building one from scratch, just a heads up.

Do the 1000w ZVS modules still need to be actively cooled? Seems like only the ones over 1000 come with fans on them, but I'm sure it would be a good thing to add one anyways.. I wouldn't think that would work well around a SAB though, but probably ok if using a flow hood or FFU right?
I wonder if you could just remotely mount the fan cooled module (under the table or something), and extend the wires going to the coil itself, with its own little stand to put in your work area or mounted just outside SAB with port hole. Or even use a remote mounted fan/radiator, so you could water cool it for adding more juice 
Anyway, I'm also wondering what 12-48v power supplies I could salvage from other devices that would work with the 1000 watt module, without spending extra money on one. A higher amp battery charger would probably work, right? Or does it need to be special\switchable, like a PC supply? I don't have any single ones over 6-700w laying around. I could add 2 of them together for over 1000w and 24v though right? I used all my good supplies for LED projects..
Also have plenty of thick copper wires laying around, and could probably wrap a nice induction coil myself. It's like they charge an extra $20-30 if the module comes with the coil..
I'm not sure what module to even get.. There's a few different brands that look slightly different.
Might say screw the induction heating altogether, and try to rig up thinner blades from disposable shaving razors to a 200w e-cig mod & atomizer head. I bet I could get it red hot in a split second, way more efficiently compared to using 1-2000watts of induction heating on a bigger scalpel blade. I already made an electronic noc loop with 26ga kanthal wire, but not sure about heating thicker blades up that way yet..
I'll go ahead and buy the cheap $15 module anyway. It will be fun to play with.
