They also have the 8SE bundle, I see, which is a bit pricier, but you get a lot more aperture bang for your buck (84% more light gathering potential + better resolution). It'd be worth considering that.
I think this is a reasonably good deal. Shopping around for the individual components, you could probably put the whole thing together more cheaply, especially if you buy some of the non-telescope accessories from OS, but as Adrian notes, there is a 'one bill' simplicity this this deal
The eyepiece/filter kit is decent, but you may soon find yourself wishing you had fewer but better quality EPs. You would already have a 25 mm Plossl that comes with the scope, so a better investment might be a good wide-field eyepiece in the 11-16mm range, and a powermate or barlow.
Note that I own the 8SE, and ALL of the gear included in that package deal (and a whole lot more...), so I know of what I speak
