Guess I am the lone voice here. I say get a real console!! and a real analog mackie counts.
I would look at a 4 bus mackie, both the 1604 and the 24x4 are decent boards. (I have done major label work on the latter, and I am currently mixing an album on the former, and I am a guy that mixes tons of records on SSLs)
If you buy and old busted ADAT you can use it as an additional 8 channel DA converter for a total of 16 outs.
In my personal experience mixing this way blows away mixing inside pro tools LE. using a real mixer for summing will help your mixes sound bigger wider and deeper, you can use the gain stage of the line inputs of the mackie as a creative tool, you can hook up a real compressor and do paralel drum compression without phasing caused by digital latency. the EQ on a cheap board will not be the best, but in a mix you should be mostly cutting anyway and they sound OK for that. If you prefer the sound of a digital EQ over the analog EQ for a certain instrument you can still use the digital EQ on that channel.
I am not an old school zealot. I mixed my first record in the box around 1991, and I mixed a project in the digital domain two weeks ago, but i still think analog mixing blows away mixing in the box. I have not done an album mixing inside ProTools HD yet, so I can not say about that, but every other situation I have worked in, analog mixing has stomped digital mixing.
