@sun oh, i heard (i think it was adrian) talking about the space being very saturated atm. I have some main stays in my list;

Adrian's Digital Basement,
8-Bit Show And Tell,
Tech Tangents,
DOS Storm,
LGR,
More Fun Making It,
Necroware,
The 8-Bit Guy,
Tony359,
Usagi Electric,
ctrl-alt-rees,


I mostly am into what Usagi Electric is doing right now, because he has those really old systems he works on (like the probably only soon to be working™ Bendix G-15 he's fixing up) and Tech Tangents (he also made that great guide on LD ripping).
