Well it depends on what you mean by "close" or "precise" or "accurate". In this thread I showed for about $2 in eBay parts you can make a self-powered AC digital voltmeter. Picture from thread copied below. The thread has a video showing it in action vs. a Z-4000 digital voltmeter readout.
The "self-powered" feature makes it like a typical analog voltmeter where no external power supply is required to power the meter itself. But to make it self-powered you need more than a bridge rectifier since the digital electronic must have power when the AC voltage crosses zero; hence the need for a capacitor. The 10 cent trimmer calibrates the meter for best accuracy around the region (voltages) of interest.
