Use a bbq igniter. Well they are both easy to mount but a latern igniter you have to keep replacing the flint and they don't work when they're wet. Plus a barbeque igniter looks cooler.

I like BBQ ignitors better because they are much more customizable, you can put the ignitor anywhere. Now a flint must be installed over two layers of pvc (for safety) and gives you no handle option.

Grill ignitors are way cooler, and would be more comfortable to operate. Just don't use cheap hair spray, it gums up the electrodes. Use starting fluid, propane, or butane.

Use bolts and nuts with stun gun ignition.
But thats just my next project.
For a basic combustion I use Lantern lighters because they almost always work with aerosals.
Grill lighters are picky and soemtimes don't light.

The problem with stun guns is that not everyone can buy them, or people think they are too expensive, I just bought 20+ stun guns and they cost the SAME as a bbq ignitor. The spendy part is when you want to make it into a good looking attachment for your cannon, and replace batteries a lot. I hate the look of a duct taped stungun with wires coming from it so i mount all of mine in a project box with a safety switch with LED, and seperate wires and switch for a trigger, here is an example:

www.preventsecurity.com has them for dirt cheap, 100,000 volts. I bought so many because I take them apart and assemble them into the box shown above. This makes it legal to sell to customers in stun gun restricted states because its no longer a weapon, it is considered an ignition source when its taken from its weapon like case.
