I would say R1Rs but I believe they are now discontinued (also 205 fronts). I've been on AD08/Rs for about 4 years now and they're fantastic all rounders. Each to their own but I wouldn't use budget tyres on my p&j *shrug*
Continentals SportContact and PremiumContract are pretty cheap and come in the right sizes. Not had them on my Elise but pretty reasonable on other cars so a pretty safe bet if it's just for road use.
