Thanks for the replies and the info. I ended up ordering the 30mm Superview. Currently my largest eyepiece is a 26mm Meade Series 4000 and it seems to be OK for most things. That's why I didn't end up going the 40mm.
Hope I've done the right thing... Will have to wait til it gets here I suppose.
I also ordered a crayford focuser. Christmas has come early.
