GoG eNVys are absolutely wonderful guns.
Get that, a small tub of lurker lube, and an NXT threaded lurker eigenbarrel in .684/NXT variety.
Have a day and she will love it for a long time.
It's comfy, VERY compact and lightweight, but not awkwardly "balanced" like a Mini.
It's also a smooth and quiet shooter.
if you're cool with a mech...
Empire ER3 and an Evil Pipe kit in spyder threads are to be found for $100 total, tops. That's what I run as a loaner for my father and for when I feel like playing silly. They're mechanical, reliable, durable and efficient guns. Great design and absolutely amazing for a low-end mech. Pretty comfy and the evil pipe kit has a .683 which works for pretty much everything and anything all the time. Feedneck clamps SUPER well and the ASA purges
and if you do it with soul and believe in pump play for beginners:
basic phantom with bottomline, hook it up to an adjustable output 13, 22, or 45ci tank should do the trick. Stick to open class if possible.
