The Pioneer RT-2044 is quite a flexible deck. It operates in 7.5 and 15 i.p.s speed. It can be configured to 2-track, 2-channel configuration with a head-block swap. It also can be calibrated for different tape types - a feature you can't always get without going to a professional open-reel deck.
Lots of info on it on the net, if you are interested.
