Do you feel that the 10 dollar universal board pullers and tapping blocks are gonna do just as goood a job as the one the flooring manufacturer sells(in my case kahrs linnea)? Im asking because the kahrs floor puller is upwards of 70 dollars!

but i would rather pay the money then end up with problems!

The puller is very heavy an stout, but for one job you don't need it.
If you mean that large heavy, "brick shaped", tapping block, that would help you alot imo. When you're finished ol'Jerry might buy it from you... I got this terrible habit of setting things down behind me instead of where I'm headed to.
