I think all those cheap relays come from the same factory in China.
If it's for something critical then I'd buy a good brand... Bosch, Potter & Brumfield, etc.
If not then just get the cheap one and keep a spare in the truck.

Cheap doesn't necessarily mean they aren't OK! I've bought relays that look like those at NAPA or other auto parts stores. Sometimes they are over $25 each, but usually I can find them for $5 - $10. Generally the all seem to work out OK.
I have wrecked some when installing the connectors. If you push too hard sometimes the spade will slip in the relay which usually breaks the connection internally. So be careful with that. Otherwise I've only ever had one relay go bad, and that was after it had been in the truck for many years.
One other thing to note, it looks like those have terminals that are normally open and termionals that are normally closed. Sometimes that's great to have, but some relays have two normally open terminal instead (one common input but two output terminals that are connected inside the relay). Sometimes that's nice too. If you only need one normally open switch either works fine. But if you are trying to do something diferent it's nice to know that both are available.

These relay sockets really clean things up compared to using spade terminals.

The ones you show will work fine. Using the first link you gave (to the AGT relays) as an example, you'll have 5 wires coming off the relay. Assuming you are using the relays for simple switching where you don't want the full electrical load to go through the switch (for instance, turning on fog lights) you'll hook them up something like this:
- Black goes to ground
- White goes to your switch. Whenever this wire is hot the relay will be on, when it's not hot the relay will be off.
- Yellow goes through a fuse to your battery positive terminal. Use the correct size fuse for the wire size you use and for the electrical load you are hooking up, but not more that the 30 or 40 amps that the relay is rated for.
- Blue goes to the thing you want the relay to turn on (for instance, the fog lights). Whenever the white wire is hot the blue wire will be connected to the yellow wire which is your fused power.
- You probably won't use the red wire. This will be turned on whenever your white wire is turned off. This is what I was talking about earlier, sometimes it's nice to have this feature. But some relays come with two blue wires and no red and sometimes that's nice too. But you can always hook two wires up to the one blue one on this relay to get the same thing.
