The prices were not really raised, there was a misprint in the catalogue, the price was about 2% below the price of the individual components. The kits are only for illustrative purposes and should be the same price as buying all components seperately. The current pricing just reflects the correction and that is why it only affects the TS24. The TS21 is a kit that Marine Depot made up and it is not anything Tunze lists or offers. On that product they had an error where the price was not raised to reflect the price increase on the Multicontroller that went into effect last fall when the new catalogue came out. Basically there wasn't a price increase, just some bad math that was corrected.
