You don't need to reinvent the wheel to understand how it works.
You can read up on the principles involved, and then, if appropriate, go
ahead and use the kit.
IMHO kit vs homemade is a time vs money issue.
A grad student is worth about $5 an hour - so if something that costs less
than $5 saves him an hour, that's money well spent. Most people seem to
think a grad students' work is free, but they don't realize that if he
wastes all his time spending weeks doing with homemade stuff that a kit
will do in a couple of days, he'll need more time to graduate and they
have to pay his stipend for another year or 2.

Of course the other issue, more relevant in industry but also in academia,
is if you're racing against another lab. If someone is hot on your tail
and you're in danger of getting scooped, spend the money to move fast and
get published / get the patent first.
