I'm in the process of testing the unit for temp control now, well used but the friend I got it from said it works fine. Missing the reversal switch, basically a little cog near the drive shaft which reverses the rotation ever two turns. This is probably a part you could order from JOBO for a couple of bucks or used as is. The plastic rack that holds the chem bottles has come unstuck and someone tried to glue it back in place. Comes with a 1540 tank as well as a tank for 4x5, 8 chem bottles and an instruction manual. Will update later today with results from the temperature check. Asking 250 plus shipping.
