Psyringe: I never had a problem with them. Downloads always worked, games bought years ago are stil accessible (even if they weren't, all games are DRM free, so the installers can be backed up manually). They are a rather small shop, perhaps their site is currently struggling with the traffic generated by the sale.
IAmSinistar: Likewise here. My main complaint with them is the lack of notification about updates. ShinyLoot is better about letting you know when a new version is out, and even Desura lets you know in a roundabout way if you track the game. Update notifications is something GOG has spoiled me on, even if that little red number tends to stick around too long.
Oh, and if anyone is looking for recommendations from this sale, the Silverfall games are fun RPGs and Joan Of Arc is good. And I love the Shining Force games on Genesis.
Alos here no Problems with DotEmu so far.

DotEMU Collection Vol.1 some 45 Oldschoold classics for €4.50
