How often do you have to service your Studer or Otari deck ? Home not pro environment.

captain_winters and ct0517, appreciate your posts.
I have been thinking about Studer and Otari half track only, not about Crown or Ampex or top Revox. Maybe I am wrong, not sure.
Yeah, 7.5 and 15 ips speed, I don't think I will need 30 ips. I asked about Maxell tape because it is sometimes available NOS, though you have to trust the seller and you don't know in what conditions the tape had been stored. I use Maxell Vertex cassette tape with my Nakamichi 682ZX, it is back coated tape and the very best available in a cassette, by far.
Living with the driving distance of your technician may be problematic. I ship my Nak to California across the country for service every few years and it doesn't come back with the alignment off, as far as I can tell. But perhaps shipping open reel deck is different situation.
I only saw pictures of Studer's inside. Appears to be a very complicated machine.
Because of the cost Otari is more realistic for me, I think, unless I decide to save up on Studer for a few more years. Would it be worth the wait ? What do you think ?

I had my Otari MX55N serviced some 4+ years ago and biased for current tape formulations.  Still going strong and measures fine.  It is in an audio (non-pro environment).

i had a couple of revox B77 i use in a mobile recording rack, proved so reliable that i sold spare to a very high end shop in San Diego..they use it with a protection copy Jacintha tape for demo...it sounds excellent 
ATR tape high speed big reels iec EQ
good techs abound on West Coast seattle to san diego because of the studio demand...

what are you seeking to do ?

the machine is the inexpensive bit........

Two things - hunting for master tape dubs and making compilations off records and even maybe some cds.
