I prefer NameCheap, though there's another one that's supposed to be pretty good and inexpensive. I keep forgetting their name, though I suppose I could search for it. I just stick with NameCheap - as I've been getting domain names from them, pretty much since the day they opened and were like a Tucows reseller - before they were actually a full-blown authorized registrar. For the .gq (and some others) ccTLD, you can just go get them free at https://freenom.com. They do have some limits, and then registering them is a bit expensive - should you want to pay for it. But, they're free. I think they charge a fee for 4 letter names? So, I'm not sure if you could secure poal.xx or anything, at least not for free.
