I like the fruity taste of habanero a lot (the red ones if that matters). But I usually get stomach pains after eating them (not that it stops me). Are there any chilis that taste similar to habanero but burns less/are easier on the stomach/have less scoville rating? 
From the excellent book Grow For Flavour there is actually a chilli called the Trinidad Perfume which is specifically cultivated to have the same flavour profile as a Habanero without the heat.     If you love the tangy, fruitiness of habanero (Scotch bonnet) peppers but can't handle heat, I have some news for you. Trinidad Perfume's golden fruits have traded gut-wrenching fire for an incredibly flavourful, aromatic citrusiness [sic]. Being sweet and with barely any capsaicin, this is the ultimate chilli-hater's chilli.   p190.

To be honest, I haven't seen them for sale around here (London).  Googling does provide a rather large number of options to buy seeds and even grown plants.
