I have been using phpbb forums for many years - usually I just pick some nice free style and use it.
However, during updates, I often end up having to select a new style due to incompatibilities etc.
I'm looking for hints where I should look for good quality styles, which are done by good designers, with high probability of continued future maintenance? I am willing to buy a style which is worth it and support the dev.
Web is full of shops offering various phpbb styles but hard to pick shops/styles which would be trustworthy according to the above-mentioned goals.
Would you please give me an advice on good and reliable styles, authors, shops?
(I know it's partly a subjective question but not too much I hope.)
