I'd say pay more up front and get a quality device, it'll save you money in the long run. For a desktop device, which I definitely recommend: budget - Arizer Q tower, and imo, best - Volcano. I like the classic. I also use a Crafty plus for a portable one, and I just use caps that I fill. Cannot recommend that enough. Helps minimize the need to clean, and I can change caps in public without anyone raising an eyebrow. But the Storz & Bickel gear is definitely pricey. However, I've had my current Volcano for 8 years, and I never turn it off. Still runs excellent, so I'd say it was worth the price and then some.
