Failing that it really depends on your system and where you want to shoot.
For indoors with power available, NOTHING will even APPROACH the price, power and versatility of even the cheapest studio light kit, and people practically give these away in the classifieds because they never use them and they take up a tonne of space.
If what you actually want is just a speedlight, then a springy cable from ebay is your best choice for close distances, you'll still get ttl with most systems and even a vintage/low spec matching flash.
Anything else you might have to spend actual money, and at this stage it's best to leapfrom 90's shit like optical/infrared first party options, and go straight to new godox stuff with lithium batteries and radio triggers. Ebay, etc is the best place to buy them, they are chink shit, real retailers also get them from the same chink sellers and add their markup.
