If your in the market for the original Tarakava set (the teal and blue pair), a seller on ebay has a set listed for $130.00 USD with free expedited shipping. That puts them at about $8.00 cheaper than the current market value for a used set according to Brick Economy, although the included shipping makes this a considerably better deal.

While I personally cannot vouch for it, the prototype Sand Tarakava that turned up on Bricklink last week and disappeared has been relisted. It is missing the prototype yellow Ruru which is believed by at least one other Sand Tarakava owner to account for the larger part of it’s value. The seller does has some credibility with the Bionicle community however, and is asking $225 USD for it.

Lastly, we have a complete set of used Bohrok Va for 67.15 after shipping. This set includes the poster, instructions and a krana for each. They average about 10 bucks each before shipping with this listing. Brick Economy suggests this is a bit higher than recent trends for used Bohrok Vah, however, the next cheapest set I found on ebay was about $91.00 shipped.
