I have one of each listed here. Frankly they perform very similarly and they are hard to tell apart physically.
But the Tak is a the more sought ofter TC and a recent one sold on Ebay for $115.00 This one comes with caps and case.
I'm offering this one for $75.00 USD Shipped to Can/USA $10 Eu and $15WW
The Teleplus is very similar optically and physically. Comes with caps only.
$35.00 USD Shipped to Can/USA $10 Eu and $15WW
