They are not a visual match, but the ATN12SA (shibata) and ATN12XE (elliptical) should fit that cartridge, and should be more readily available than the TKN2.
Thats exactly what I'm after, something more readily available. I have since learned a TKN3 will work also but probably much the same as the TKN2 (able to find but pricey). I will check into those others THANKS!
