wow a couple of thousand per track? thats one pricey digital machine.... Unless your talking about 3348's and D827's from the early/mid 90's

and the scary thing is that the 3348's are selling for under $8k now days....I just saw a pair with less than 1500 hours on ea sell for $9200
you may be surprised at how good even a MX2424 can sound as long as you are working with a decent front end. Dont get me wrong....im very much pro analog, as a matter of fact I typicaly use both depending on needs and requirements.
you can even get prism converters at less than $1k/channel
oh and if you DO want an analog machine....I have seen decent sony/mci 8 track one inch machines sell for under $1k. Hell I bought one a few years ago for $600....
understand that unless you are a tinkerer and understand some basics on the maintenance of these machines I wouldnt completely recommend one considering some of the other options out there. If you dont mind dealing with electronic and mechanical cal or atleast not intimmidated at the thought then its not as bad. MRL's even today can be a bit costly, toss in a tentelomter and a few other basic tools and you would be ok.
Oh and dont underestimate things lke space requirements, moving them around? power consumption, head life, meter bulbs always burn out. etc.....even the JH110 8 track weighed about 250 pounds.
