As I said above, I find Mo-Fi to be hit and miss, and I agree that Analogue Productions is quite consistently very good But, there have been many other labels doing reissues that have been very good too, such as Classic Records and King Records, and some that have many great reissues in their catalogue even if all are not great, such as JVC and Toshiba (to name two labels I have not mentioned above). For a lot of really great records, such as the old Blue Note catalogue, one must collect reissues unless one is willing to spend thousands of dollars on originals (I don't own a single original Blue Note). There are currently active companies that make fantastic reissues of some very important albums that are extremely expensive when originally issued, never mind what they end up costing as collector items later (e.g., the reissues made by the Electric Recording Company).
Once you get up into crazy price collecting, it might make sense going to reel to reel tape. I would never go that route myself, but, I've heard direct copies of master tapes that cost north of $1,000 that are so much more open, vivid and alive than LPs. I am too poor and too lazy to ever want to deal with tape.
