Mate,
Something is only good value if:
1. You either need it or know of someone (ie this is a market) that does, and,
2. It is at a significant discount to the rest of the available items currently on the market that provide the near-same functionality.
With the above in mind (and taking your word for it that amongst other vendors, the cost of this source-code is cheap for similar functioning items), the only question remains: 'Do YOU need it ?'.
At this point, I'm consciously making an effort not to attempt to tie you to the actual vendor.
If you can answer the above question in the affirmative, then for you, maybe, it is a steal....
Waiting with baited hello-there....
