New to vaping, looking for recommendations

I've been a stoner for forever but I just moved into a place where I can't smoke inside. My roommate doesn't care if I do on the community patio, he just doesn't want the apartment to smell like weed. I thought a good solution would be to buy a vape and start smoking primarily wax and shatter with it. So what I'm looking for: Price range of $100-150 Something that won't make me smell if that's possible.
Something that works well with concentrates.
Easy to transport in a back pack. Don't mind buying a case if I need to.
Easy to use. I'm going to be loading and using it at parks and stuff so I won't be having a coffee table to spread out on. I will be the only person using it, and I don't smoke a whole lot. I just need to take a few tokes on my walk home from work or when I step out for a minute.
Also I live in Denver so I don't really have restrictions on products or getting flower or concentrates. Thanks in advance
