To justify spending 200 euros: 200 euros is really not much in the grand scheme of things and considering the above, I think it's worth the expense. When asking for links and you have a good looking site, your requests are more likely to be answered than if you have a garbage-looking site.
Regarding whether it's a wise investment of my time, it's harder to say. There's the time developing it but also (mostly) marketing it, link building etc. I think at some point you have to go with your guts, you will never have all the data you wish at the beginning. Then if it works really well, I can look into adding more features, more calculators, more content etc...
In my mostly-unqualified-to-comment-opinion, that is.
I decided to spend a minimum amount of time on it to just test it out: just a form and a little description. The only decoration was that the text was centered and navy :)
Results: only 4 sign ups over 3 months..mostly from friends and family.
Then I made a nicer design, added content, and voila got about 30 sign ups in about 1 month through google search results. Added benefit is that now I'm not embarrassed to promote the site which of course has yielded many more sign ups.
To sum up: an effort invested in design pays off since good looks provide a hint of legitimacy. Generally speaking :)
