Hi Eric,
Welcome to the Forum. Most of the people here like Denon Receivers in addition to Marantz, Yamaha, and few who like Sony. If you could push up a level or two on the Denon Receiver, you'd get more features for your money. The Denon AVR-S730H is only $100 more at Best Buy locally.
Or you may want to consider Gibby's Electronics in Ontario. They are the only Authorised "B" Stock Denon seller in Canada. They sell regular stock too. They typically offer free shipping and there is no provincial sales tax. They warrant the Receiver for a year.

The B Stock Denon AVR-S730H is only $20 more than the AVR-S530BT at London Drugs; and definitely a step up. If you can spend $399 they also have the B Stock AVR-S930H which is where I'd suggest you go.
I live in Metro Vancouver & I have a London Drugs a few blocks from my house. (I buy BluRay Concert disks from time to time there; as well as regular Drug Store stuff.) The reason I know about Gibby's is I've installed Atmos Speakers during our recent renovation, and now have an 11.2 set up but only a Denon AVR-S9O0W which is 7.2 and doesn't do Atmos. I've been holding off buying a B stock (or any) AVR-X6400H until I can find one locally, and hear an Atmos setup. (I wired the in Ceiling Speakers in when the Renovation was going on, and installed them after the new Ceiling went up. It was do it now, or never, sort of thing.)
In addition to the Denon AVR-S9O0W, I have an old 5.1 Denon AVR-1612 entry level receiver in my basement system, and a couple of 5.1 Sony Receivers (Sony STR- DN1050 in the Family Room & a Sony STR-DN860 elsewhere) as I'm a bit of a nut for Home Theater. I'm pleased with all of them.
You are doing the right thing by researching first before buying. A gradual approach where you add equipment as you can afford it is the right way to go. Check out Craigslist locally for used speakers when you are ready.
Good luck building your system.
