i was in the same boat as OP.
i picked up a cheap-o pusher and it died the 2nd time i used it.
i was thinking about replacing a bunch of my pistol sites and with the black friday sales i ended up buying a couple sites for a couple different pistols so i was trapped, i had to get a decent site tool.
i ended up ordering this from Brownells.
i found it in Canada for $280-$350 but $120US from Brownells even with shipping and conversion i save over $100.
all in i think it cost me like $170.
i have 5 of my own to do and my dad wants me to do 3-4 of his and a co-worker wants one of his done, right there im into this for $12 a pistol and cost to me will just get cheaper every time i use it.
i think its a safe investment.
buy good quality and pay only once, meh.
