Im starting an ebay gadget store. what are some cool fun things to sell?

well technically ive already started, but now, ive made enough profits to begin expanding.

At the moment i sell 70mw green laser modules (not pointer pens), carbon graphite rods 5/7/10mm wide at any length and from time to time i try and get rid off my liquid a$$ stink spray, though people tend not to buy that as postage is $6, and lastly long range, but very cheap, 433mhz receiver transmitter pairs . All of this , from within australia, i plan on selling things which are awsome, as well as generally inaccessible by many australians.

Currently i intent to buy up 6v spark gap ignitors , identical to those on sparkfun, different coloured laser modules, titanium to weld to my MMO anode mesht cuts, more wireless receiver/transmitter pairs, though, this time, toggle/momentary ones, currently my ones are latching, i plan on buying small shockers, and lastly, Nitrates, Aluminium powder, sulfur, and all those chems which are so hard to find in australia. Also, i will start buying more, and in larger amounts, thermochromic pigment.
I also plan on building DC-DC HV converters, for charging coil gun capacitors, (based on the instructable of the same name, once i get permission to use the schematic to base my design off to sell), small shocker modules (to make taser things from), Various oscillators, like flyback ones, 3D printing services and 1W regulated 808nm burner modules.

Now, ever since i discovered the spark gap ignitor wholesaler, ive been thinking, "what else could i sell thats awsome and hard to come by?", but legal too, this is ebay after all.

I would really like some help in finding things which arent especially expensive or big (im not buying stuff which costs like $100 a peice), but also things you would like to see sold in your local gadget stores.

Really, just anything in this general catagory, stuff which is really awsome or very hard to get, either in australia or anywhere, but not illegal. like novelty gadgets, or things which do amazing things, such as mini spy cam bugs or something.
I really need help, i know what kind of things I LIKE, and want, but not what others like and want.

please help me out!
