Hi,
I'm Patrice and I look like you Cam86, I have opened the post on the French forum, since the beginning of your subject I read you without speaking.
By the way, hello Gilles

.
My PCB are achieving by PCBWAY they were costing € 20 for 5 pieces with delivery, I'm surprised for the price you speak above.
For soldering not to worry it is not hard, I started by voltage regulators to take action and be sure to have not a short circuit, after the rest, I has a small soldering station cheap.
I find it unfortunate not to weld ourselves it removes the fun of building and it's easy.
Sorry for my english
