How about the aluminium blocks that fit into Techne or similar dri-block
heaters?  Phillip Harris list a 20 x 1.5ml block for 78UKpounds (Techne) or
a Grant version that is for 24 x 1.5ml, 59UKpounds.  We use one for exactly
the purpose you suggest.  Its nice to tape a bit of
foam/polystyrene/whatever around it so's your hands don't stick to the
metal :-)
