Hi Brancaslim,
There are few things to consider when deciding wheter or not to invest in support software.
1) Without a software that keeps track of your play how do you keep track of your progress or lack of it? Finding leaks and points of improvement usually requires measuring your performance. This alone was enough of a reason for me to buy a third party tool.
2) How trivial is the price of the software to you? If spending 70-100 dollars makes no difference to you then go for it. But if it's money taken out from something more important then you can always postpone the purchase. After all, as useful as it is, the software does not perform miracles.
3) Where do you play? Many poker rooms ban the use of third party software, and if you play in such enviroment then the only usefulness of the software comes from analyzing your own
hands. You should always read carefully your poker room's TOS before using any third party tool.
4) You should always think poker in long term. You migh not see the same opponents tomorrow or the day after, but if you keep grinding the same levels over and over, sooner or later you will see the same players again, and then the usefulness of the software might start to pay off.
