Recommendation? Wood stabilizing service in Europe?

[FredyCro]

Any of you guys know or have a first hand experience with a wood stabilizing service in Europe?

I tried the home procedure but wasn't happy with the final product when compared to a professional piece.

For now I found that jatagan.eu (Czech) and holzstabilisieren.de (Germany) offer the service. Any experience with them? Thank you for your input.
