Me too. Bar-end shifters are the ideal, followed closely by clamp-on downtube shifters.
I have tried STI but didn't like it for a variety of reasons: somewhat hard to shift from the drops (especially the upshifts); the brake lever is acting a bit strangely. Besides STI on a snowy or frozen bike is not the best idea.
BTW, for downtube shifters, I like the shifters to be much higher than the usual position for the braze-ons
