Do you guys go all out on a high dollar gage or will a cheaper model suffice? I'm looking at this one: General Tools PTH8707 Humidity Meter-Digital. Sorry I couldn't seem to get the pic or link on here but it's about $40 and is a small handheld/pocket unit and looks to be nice. I was just wondering if a humidity gage is something that you could get away with spending like only $10-$15 on and still have good reliable readings, or if it's recommended to splurge on something better. Thanks
