i've got a speed pro 07, had it a year and its excellent. Can cover 18 miles over one hour no problem. Wheels have survived nasty potholes, i'm not too heavy and sometimes do ride out of the saddle but i keep most of my weight on the pedals (i'm slightly wary of the handlepost latch). The stelvio tyres are great, the other day noticed a hole in the back one 3mm wide and about 4mm deep (!) still no puncture! Plugged the hole with silicon sealant. I sold my old claud butler for £140, got the pro new for £620 so a £750 bike only 'really' cost me £480! I'll deffo get another Dahon in the future.
