I'd say it looks worth your while. That's a very common style. MANY of the commercially available airbrush compressors are just a variety of brand names slapped onto the same model, coming out of one or a few (Chinese?) factories. The main differences you see in price hinge on the warranty/support attached, name recognition, and whether they plumbed the base model into a tank. Remove the tank and the logo from the actual compressor component, replace the bolts with rubber feet, and slap a Central Pneumatic sticker on - suddenly, it's the one they sell at Harbor Freight that I've used for several years. Look at a dozen Amazon listings under a dozen brand names and you'll notice how strikingly similar they all seem to look...
Broadly speaking, they all work just fine. Having a tank is preferable, but not strictly necessary. People talk about it reducing pulsation, but with the degree of control most of us have, you'd be hard-pressed to notice that over hand jitters, with nothing more than a regulator and 6' of hose to smooth things out. It IS a potential factor, though, so weight it as you see fit.
The bigger benefit, in my mind, is potential longevity. So long as you remember to occasionally drain condensation from the tank, you can leave it at pressure. This means that the weak little oilless pump only works hard once per fill, then just occasionally pops on for a few seconds to top off the tank. Less heat buildup and less wear on the relatively cheap guts of the pump.
