but in general ur requirements are pretty ok, one bag u can try is:
the sinking barge & the keystone - this 2 are the smallest bag from crumpler and just enuff to fit ur camcorder and laptop.
or the computrekker AW from lowepro will do just fine for u.
i m not too sure abt the pricing, but the crumpler is arnd $200 while the lowepro should be arnd $150
