Blood Parrots are of an unknown origin, but are commonly said to have parrot and texas cichlid in the bloodline, along with one other species that escapes me. So if you don't like the parrot shape, you may want to stay away from the ones you saw at Nautilus, though I'm no expert on how the genes all work out in crossbreeds.
I've seen the jag at Pet Time, and agree, $70 is just too much for a freshwater fish, if you're willing to be patient and raise one from a juvenile. If someone is just looking for a big fish right now, however, it might be worth it to someone.
Petsmart has always been decent for cichlids in my experience with them, but I also add rift lake salt to my cichlid tanks to better duplicate the conditions in Lake Malawi, and salt happens to be a natural remedy for many conditions that are said to be found in the Petsmart tanks. If you plan on quarantining the fish before adding it to your main tank (which I highly recommend), or using cichlid salt, I wouldn't worry much about it. The quality of their selection often leaves much to be desired though. I have some beautiful Firemouth from Petsmart, but I waited until they had them at the level of quality I wanted, rather than just buying them because that's what was there when I wanted fish. Patience is everything in this hobby!
I like Firemouth cichlids. It's the whole neck flap thing, it just adds another dimension to the character and attitude of the fish, but they may be too small for what you're trying to put together. I honestly don't have too much experience with SA/CA fish, aside from Firemouth, HRP, and Rainbow cichlids, due to the fact that my CA/SA tank is only 60g and heavily planted, so I had to find smaller, plant friendly fish.
