Laptop Bag for HP dv6700t

I have just ordered a HP dv6700t and am now in the process of finding a smart bag to carry it around. Belkin Messenger Bag seems to fit my requirement of a semi-casual bag which doesn't appear college-like (I'm a working professional) and at the same time, doesn't seem too formal or boring. Now here are my questions:

1. Does the Belkin 15.4" Messenger Bag easily accomodate HP dv6700t with place for standard accessories to fit in well? Or should the 17" bag be considered?

2. I also came across a Belkin Energy Messenger Bag which is "designed for Dell". How is this different from their standard bag and will this be suitable for my HP laptop?

3. What are the other good brands (in US) which fall into the under-$50 range and can meet my requirements?

4. Where can I find the best deals or discount coupons for Laptop bags?

Help the newbie!

 

1. It probably will.
2. No idea. Dell just recommends this model, I guess.
3. Consider the Samsonite L45.
4. EBags.com is a good place to look.
