There are quite cheap vaporizers out there that do the job, maybe not as well as the higher end devices, but a huge improvement over joints, IMO. Here is one example:
Atmos Jump Vaporizer - Shop Now | TVAPE Store Canada (torontovaporizer.ca)
I have been using mine intermittently for over two years, and it is still perfect. You do not have to spend a pile of money to try vaping. Some time after I started with the Atmos, I bought an AirII which is now my main vape, but the Atmos gets used regularly as well.
If you are good for a bit more money, I also highly recommend the Air11 or the Argo.
