Too much aggression for a techer to do well. Prices are high because such techers as there are have had to waste countless turns building and re-building.
Leave us in peace, guys and you can have all the tech your heart may desire (but not land, go elsewhere for that please - no thin techer, someone nice and FAT).
Theres gotta be 100k in techers, unless players I oped comverted tech prices stayed high due to players holding turns like myself until my stuff sold at "fair" prices.
