Otaris are very good RR machines and 1/2" 2trk(one-way stereo) will be great enough for recording and playback.
Nowdays they're all vintage "toys" replaced by much more versatile digital hard disk units such as Alesis.
As to 1" machines you can also find them among Otari but they are too large and getting the bobins for such machine will definitely be a hassle while 1/2" you can still find in music stores such as Sam Ash Agfa or Basf.
The latest Otari is MX5050-BIII which comes either 1/2" or 1/4" 1, 2, 4 and multi-track.
