Many lock companies are fond of using this kind of terminology, it makes their locks sound more impressive when they're actually just bog standard stuff. Master lock, for example, touts their M5 commercial lock as having a "4 pin tumbler mechanism for maximum pick resistance". It's a 4 pin cylinder with all standard pins and crappy tolerances; you'd be hard pressed to spend more than 30 seconds opening one.
Sterling are far from high security, trust me... it's just a standard lock. It might have spools in it, but I've picked a couple before and they were just standard pins, mind you the newer ones might have spools for all I know. Whereas I doubt it, you can always be surprised... so what I'm saying is, they probably don't have spools, but there is a small chance they might! Just get one anyway and see how it picks

The Yale will definately have spools in it. Their kitemarked cylinders use a kind of serrated pins, but the one you're looking at is a standard replacement so it'll have between 2 and 4 spools (most likely just 2). As for the unbranded one you linked to, it's a 99% chance that it'll be all regular pins. Again, there is a rare occasion when you get a cheapy one with spools in it but almost all of them are just regular old pins.
And yes, the double sided euros are the ones you need special tools for. Rim cylinders like the other 3 can be repinned with a plug follower of around 11-12mm diameter and basic tweezers.
