you must be going to buy a quality one. Mine was $39-50. I had a look on Trade Tools site, and they don't seem to have them listed at the moment. See how you go searching for an AB-2 Bearing Puller 24-55mm. Trade Tools' sticker calls it an Armature Bearing Puller TOG-AB-2.
Not wishing to 'teach Granny to suck eggs' and apologies in advance if you know this, but I found it worked best putting some tension onto the bearing, and then giving the shaft of the puller a tap with a hammer, more tension, more taps etc.
I am sure someone on here posted that they removed these with a grinder too - there was something about safety googles having been required but not used. Traditionally, grind a bit of a weak spot into the race, having first removed the cage and the rollers, and then a judicious tap with cold chisel and hammer to crack the race off.
Once again, noting that you are installing lockers yourself, apologies if you know all this. Oh yeah, did you find the excellent thread with photos that are on here somewhere?
