We routinely use QIAEX to purify from TBE/agarose with no ill effects.  
However, given that I'm currently in the midst of a large project, this would 
have been expensive for my 2-round PCR expts.  So I just cut the bands out of 
a gel, melted, took 5 - 10 ul of the agarose and plonked it straight into a 50 
ul PCR rxn.  Superb.
