@Pumpkinguy, I saw a video on YouTube by Painless360 that gave me some really good ideas on LED lighting.
What you are considering is fine as you are going with the bigger and brighter "5050" size LED (I made the mistake of buying and installing the 3528 which is smaller and more LEDs per cm, but not as bright). However, you are going the expensive route. You can buy a 5m reel for significantly less than the price I see listed on your link ($20 per 20 inch strip seems a little steep to me). Also, it appears you're not considering the waterproof (ie, outdoors) version.
I purchased my reels (white and red) on Ebay...seems the easiest place to find them. Here's an example link:

At 4.79 GBP (about $7.50) for a fricken reel of 5m, seems to be the much better value. Yes, you have to work with it a bit and peel back the waterproofing from the pads you want to solder to, but I found it to be rather fun.
Have fun with the lighting project and the best of luck!
