I just bought a Tecomec chain breaker and rivet spinner from a local shop for $121 out the door for the pair, I have only shortened a couple of chains so far, but they seem to be quality tools.
Good deal!
eBay seller ArcherPlus has the set for $130, shipped (in blue), or $160, shipped (in red).
I think that these might be the most widely used, current, models.
The replacement spinner anvils, breaker punches, etc., are widely available, due to the popularity.
My sets have paid for themselves several time over, repairing and resizing loops. And, they still have at least 50% resale value, if I ever decide to sell them.
