I can only recommend the TM one. I've never tried other brands, but I've never been a fan of buying copies, especially when it comes to electronics like this.
Best "bang for the buck" may be a clone, as it's obviously cheaper, but there is no guarantee it can keep up to high ROF setups, it may suck up more power, or the electronics may not be as durable.
Any retailers you would recommend that have the TM tracer silencer?
