RMS means "root mean square". When you read 120 volts. The actual "peak to peak" voltage is something like 169 volts (give or take a few volts). So, the nominal voltages that we talk about every day are RMS values.
Anyway, enough of that. I'm a Fluke lover. My personal meter is a Fluke. My company bought a Greenlee for me, and though I like my Fluke better, it does a reasonable job for a lot less money. I'm sure one day that Greenlee is going to "give up the ghost", but my Fluke just keeps going and going. You may be hard pressed to find a Fluke for $150 or less. I can't say for sure because I haven't priced them lately. So, Greenlee may be your best option.
By the way, welcome aboard,
