Adding Blown-In Insulation Myself

I would like to add insulation to my attic this Fall (approx. 2400 sq ft). It appears that the blown-in type would be the easiest and most cost effective if I did it myself (vs. fiberglass batts). I would like to stay away from the recycled & treated newspaper insulation and stick with the cellulose/fiberglass (like Certainteed's InsulSafe 4). Problem is the local building suppliers will only sell this product to contractors and the local Lowes home improvement store only offers the recycled newspaper material and blower.

1. Any ideas where I can buy the InsulSafe 4 or similar material and blower (rent it)?
2. Any guesses as to the cost difference between hiring a contractor vs. installing it myself?

You are running into a huge problem. The machine required to blow an insulation like InsulSafe4 (fiberglass) is totally different than the machine required to blow cellulose (recycled newspaper, Cocoon, etc.). Lowes, Home Depot, etc., only sell the cellulose, and the machines they loan you to blow it are for that product.

In my opinion, cellulose is better than fiberglass. Cellulose is 'flame retardant'; fiberglass is 'flame resistant'. What that means is that fiberglass will eventually burn. Cellulose won't. Critters will nest in fiberglass, whereas they won't in cellulose.
