I'll toss in my two cents here...
I have a 10x10 Kodiak and we are going to add a 10x14 Kodiak for this year and hand the 10x10 over to our son for his first burn. I would recommend a Kodiak over the Springbar (same design) because the Kodiak has a lot more features in terms of build and accessories.
The biggest difference between the SB model you are looking at and the Kodiak of the same size is that the Kodiak utilizes D shaped doors and has 2 of them. The SB has a single door that is the traditional zip down the middle style. The Kodiak also has 4 windows total (2 built into the doors). The SB has two including the door one. While you may not think about it much, having a front and back door is very handy if there are 2 or 3 campers in the tent.
For Pensic, (merced out of Ansteora with my Household for Middle Kingdom 2 years), the extra windows and the included awning on the Kodiak (not available for the SB that size) will be a very nice addition. At Burning Man, zip all the windows shut and open the top vents (not available on the SB) and about the only dust you'll have inside is what you track in with you. If it calms down at night, open up all those windows and enjoy some fresh air.
The kodiak also comes with gear a gear locker, storage pockets and 4 D rings inside the tent. We hung a fish net and used it for extra clothing storage. The Springbar does not offer these
Technical aspects, the Kodiak has a thicker floor and the seams are welded, not stitched. If its a wet Pensic, you will have a good chance of water seepage in the Springbar. Kodiak uses steel poles, not aluminum. Yes, they are heavier, but they are also stronger. Kodiak also gives you 12" steel stakes instead of plastic ones like Springbar.
I would also encourage you to consider spending the extra $100 and go with the 10x10 Kodiak. While it doesn't sound like much, that extra square footage can be a really nice thing.
For shading, garden shade fabric works pretty good. A lot cheaper than aluminet and its pretty much available at any large retailer with a garden supply section. Home Depot, Wal-Mart, etc. If you can pack it, building a frame out of something simple like PVC to keep the shade off the canvas would do wonders.
