skywatcher or celestron!

Hello All..
Thinking of buying myself a telescope for xmas,i have had one before,russion
tal1,but i was wondering what the skywatcher series is like for optical
quality,i want the best optics for my money,mount and things like that not
as bothered about as they can be upgraded later if required.
I think i want a refractor,what would yuor opinions be for the best
refractor under £200..
Choices i have seen a-
celestron firstscope 80.
skywatcher evostar 90
skywatcher startravel 80 short tube..
Please can i have your veiws on the optical quiality of these scopes.
Many Thanks
Gary.
