skywatcher flex auto 200

[tomlines]

ill be purchasing this scope in the coming days and to the best of my knowledge comes with a standard stock 25mm and 10mm

this may be a very stupid question but whats the difference between the 2'' eyepieces and the 1.25'' eyepieces

i understand my new scope will take both and looking at buying some new eyepieces later on in the year and basically wondering if the 2'' versions would have big advantages over the 1.25'' ones?

the 2'' one sseem more expensive (i assume as there is more of all materials involved)

would the field of view and quality be better in a 2'' EP?

thanks for any help in advance and if any one can suggest a moderatly cheap eye piece replacments for teh stock ones that would be very helpful :-)

thanks guys
