Hi @DebbieM - here’s a link to my concentrates blog. The very first one is a basic qwet using only Everclear and a little patience 
Tag me if you have any questions! It’s super easy and you won’t believe how strong that stuff is! Approximately 750mg of THC per Gram!
Everclear here is not super cheap. I pay $45-50 for a handle.
I now use a Source Turbo (it’s pricey at $600) but if you do it enough, it reclaims about 85% of your alcohol each time so I paid for mine in about 20 runs (I’m not the best at math (especially when I first wake up LOL) but that’s about what I calculated… @blackthumbbetty can say better for sure.
The basic QWET sounds like what you want to try.
