I have no personal experience with that thing, but man it looks so much better as a starter dripper than the IGO-L that I started with...aha. It's a 510, so it should fit on your Spinners, however you may find that the spinners don't push enough power to really get that "dripper experience" going.
However, that being said, I think you should go for it. With your budget, that looks like a perfect started RDA. Once you get comfortable building coils, checking your builds (resistance and Ohm's law, make sure you don't push your spinners too hard), and setting your wicks then you can just grab a cheap-o clone Mechanical with a good 18650 (VTC5/Efest 35A/Subohm Cell/lots of others do your research before buying) and a clone of a higher end RDA. If you feel like this is something you get into...then embrace the GAS! (Gear acquisition syndrome).
Best of luck, let us know how it goes!
PS: Always be safe. Make sure you're building coils that are within a safe range for your batteries (in your case the Spinners). Do your homework, always. If in doubt, it's better to be safe than sorry.
