The Tascam M512 & M520, no doubt, would be the righteous boards to have.
They were the topline boards of their class, [vintage, discrete controls, VU-meters, 8-buss, etc]. It hardly gets any better than that. Anyway, $600-$650 for a prime M520 is a fantastic deal, any way you slice it, and with it, you've gone from 'zero-to-pro' in about 6 seconds! As I said, if I could justify the cost, in my currently unemployed state, I'd pick up that very M520, and I was scoping it heavily before it got mentioned on this board. However, not only would I have to justify the cost to the 'bank', but I'd have to clear the decks of about 3-M30's, several Portastudios, and lots of other stuff, just to make it fit in my room!
PS: I also passed on a 'mint-in-box' MS-16, that came with rack, dbx units AND about 32 REELS of 1" TAPE, all for just over $1800. I REALLY wanted this one, but again, I'd have to justify $2K cost to the 'bank', and also the gear was in like OHIO, or some distant place, where in-person pickup would have been a MAJOR road trip!
Anyway, re: M520 and MS-16, despite my salivating at the 'puter, wishing I could just pop for these items, I have passed on bidding, for the time being. The MS-16 has bid-away for about $1850, but the M520 is still available for $600-$650, and IMO that's a super deal. How much was this board originally? My guess is about $12K, new. $650 is a great deal for that item, and the seller knows that it's a good price, and is willing to wheel & deal! I say, go for it!
Also, mentioning back to the M30 and M35, these boards can commonly be found for ~$100, more or less, avg ~$150., which is admittedly much less of a board than an M520, but still funtional and a much easier cost to justify to the 'bank'.
