I want to get Hotbird in my 'week day' house and am thinking about smaller sized dishes. Is there any major difference in performance between an Arcon Tweety or any other small dish or just a normal mini-dish (apart from the large price of course).

Ideally I would like to get the reception through the window but that may not be possible.

Any thoughts?

Tweety is the bird that Sylvester wants to eat - I think you mean Sweety!!

Anyway, the Sweety is supposed to have better performance than a normal dish of that size as it uses the secondary reflector principle to get extra gain (it's similar to a Gregorian dish but for the life of me I can't think of the correct name). Unfortunately the dish is very small to start of with and even with this extra gain it's only equivalent to a middling to small standard dish of about 60cm. I believe that there is a larger version which might be better.

Reception through a window is possible but difficult. Change the glass to polycarbonate, an RF transparent material, and you might get away with a standard dish. Leave the glass and you'll need a larger dish than standard. If it's double glazed probably best to forget about it.
