Just to compliment what has already been said, the 10" is the same length as a solid tube 8" 1.2m Mine used to fit into the back of a Mazda MX6 coupe. The weight and size is comparable to the 8". The 10" will show you a lot more as you can see it without having to strain to see it.
E.G. I can see the flame nebula JUST in perfect dark skies. Running man on M42 is visable, Cent A is clearly visible as is pinwheel m83. in a 8" scope flame nebula no, running man you can semi make it out, cent a kind of, pinwheel kind of.
If you can get the 10 great, if you cant the 8 will be a good scope too.
The difference between the F ratios will be collimation accuracy. The lower the F# the more critical it is to have your collimation spot on. Don't see this as a deal breaker though, some decent collimation equipment will make light and accurate work of the job. Just don't skimp and get a 40 dollar laser this will almost guarantee the same kind of return in views Further more you will get brighter images with the faster F# (well that is my experience)...
Good luck
