510 ohm meter.
How much do you want to spend? I'm personally planning to get the coil master 521 tab when funds are available for it. Geekvape makes one kind of like it, without the leads to check wire resistance. But it checks ohms, has a nice build deck and can fire the coil. The coil master is around $40, the Geekvape is around $30.
The normal ohm checkers start around $5 and go up from there. But keep in mind, you will get what you pay for!
