As you probably know, something cannot be created out of
nothing. A solution/package will not be easy to install
just because you paid more money for it. Whichever way
you go, you do have to have the skills. It is true, that
some packages require more skills than others. Some
packages that you pay for actually require less skill to
administer than the ones that are free or cost very
little, but this is not always the case. As for myself,
I would rather improve my skills than convince the
management to buy a package that requires less skill to
get to work, for the following reasons:

- Improved skills mean wider job opportunities
- The management may actually consider giving you some
of the money they saved by not buying the expensive
- The more skills your job requires, the harder it is to
replace you - job security

Running stuff that could be maintained by a low-skilled
person is not in your interest, if you are not one.
Otherwise, the management will try to replace you with
someone who would work for less money.
