http://www.ebcbrakesdirect.com are a good bet. Wether you go for the standard brakes which are pretty darn good or something a bit better like greenstuff.
Standard will easily match FIAT quality and be a lot cheaper.
Are you fitting yourself? or are you looking for us to point you at a garage to do the whole deal? If so any independant will be able to offer you a good price.
Yes, Red Dot, If indeed you do want the "best brakes"
If you want normal brakes or "breaks" i got front discs and pads for £40ish at brakes4u.co.uk and they are as good as the standard ones and work perfectly well for me.
