FatWallet/SlickDeals HT setup!

hey everyone... i'm almost done with my first HT setup ever... i built it from the floor up and pinched every penny i could along the way... i wanted to know if i did ok, or if i wound up with a bunch of crap! anyway, here's what i've got, what i paid (inclusive of tax/shipping), and the msrp (although msrp is a little misleading considering some of my components are older models, although still new):

Pioneer PDP-507CMX 50" Plasma Display (MSRP $6255.00)
Key Digital KD-PC2 Video Processing Card (MSRP $999.00)
$1913.00

Sony STR-DG1000 Receiver (MSRP $799.00)
$517.00

BIC Acoustech H-100 12" 500 Watt Powered Subwoofer (MSRP $439.00)
$225.00

Polk Audio R50 Front Speakers (x2) (MSRP $639.95)
$167.74

Polk Audio CS125 Center Channel Speaker (MSRP $199.00)
$86.00

Polk Audio R15 Rear Surround Speakers (x2) (MSRP $179.95)
$60.00

Logitech Harmony 550 Universal Remote (MSRP $129.99)
$49.99

Griffin TuneCenter iPod Dock (MSRP $129.99)
$83.95

Bush BUS AD53940 Stanford Audio Cabinet (MSRP $459.95)
$192.41

Monoprice Adjustable Tilting Wall Mount (MSRP $59.58)
$40.29

Total: $3336.38 (MSRP $10160.42)

my budget is $3500 (which, as you all know, means it started out as $3000) and i've still got to buy all my cables and run a clock outlet to behind the plasma... for now (and for at least the next few years) my existing LG DR1F9H 1080i upconverting DVD player and Scientific Atlanta 8300HD STB will be driving the home theater and an iPod via the TuneCenter will be doing most of the music...

please let me know what you think...

thanks for the feedback! i figured with all the audiophiles here that i'd surely get laughed off the forum because my receiver's timbre didn't match my sub's impedance.

(note: i *think* the preceding sentence makes no sense; if i'm wrong and i actually stumbled upon something that does make sense, i apologize!)
