I've got 4 TCU's (two Metolius, two Wired Bliss) plus one 4CU (Metolius) surplus to my needs.
$15 each or the lot for $60, plus postage.
All wires in excellent condition and cams articulate smoothly.

Also surplus to my needs, I've got a brand new (manufacturer's pamphlet still attached) size 3 Wild Country Helium cam for sale. $70 

Or, if you happen to have a new .3 Camalot that you don't need I'm happy to swap as I need that size.

Call or text 0407 310 287 if you're interested.
