Since my last post I bought modules from @100000bps, @tonito, @Slocap and @LiquidYzer (sorry man but I can't tag you properly).
Everything went smooth, no problems at all.
I also bought a Monsoon from @PinPinKula, communications could be faster but the module safely arrived and it's a flawless build.
Somehow I totally missed this here and only ever used the "thumbs up" feature. So belated props for the following sellers that I had a great experience with in the last months:
@A.S. (very thoughtful packaging)
@patr (super fast and nice)
@EkoC (was really great and helpful)
@zfrucht (kickstarted DIY for me)
@wavecircle (nice and understanding)
I guess I miss a whole bunch more from which I already deleted messages, but will try and post here too if I meet more great sellers like these.
