Scott, 

I cannot use a random effects estimator because of strong correlation
between the individual effects and the regressors - heterogeneity bias
according to Chamberlain. On the other hand, the fixed effects estimator
throws out all the between variation. I know that there are ways of taking
into account the heterogeneity bias, but do not know how to do it - that is
why I wanted to know if anybody else does.

Isn't the random effects estimator (xtreg, re) a weighted averaged of the 
between and within results? 

Have you taken look at xtgee - it allows for variety of correlation
structures 
and semi-robust standard errors, though it is a population-averaged
estimator. 

I hope this helps, 
Scott
