For anything non-complicated I'd recommend http://dirtypcbs.com at only $14 for 10 boards (50x50 mm) and $25 for 10 boards (100x100 mm), regular HASL. +$15 for ENIG. +$29 for fast DHL shipping (Also free Hong Kong Airmail if you are willing to wait 14-30 days).
At least I'm happy with what I got.
can also confirm that
.
i've been making small 2 layer pcb's (but with lots on them, going right down to the finest traces, vias, ... they allow), and had great results so far
.
Also being allowed to panelize them for free with mousebites when it's 2 layer is awesome
. plenty of boards to experiment on for hardly any money at all.
After placing the order, it takes about a month for the boards to reach europe, not too bad
.
I also love how they give you no hassle at all. My first board with them (i was a beginner), had vias that were too small. They just manufactured it, no questions asked, not sure if they just went beyond their specs and used a smaller drill or so, but i got fully working boards
