New to weed, having trouble finding the right vape pen

Hey there! So I am pretty new to weed. (I never liked smoking but tried a disposable vape pen a few months ago and realized it helped with my back pain and insomnia.)

I am planning to get some cartridges at a dispensary. But I'm hoping for a pen I can use them with that is similar to the disposable pen: no button, just turn it on and inhale to draw. Does this exist? Any recommendations?
