If it has a temperature control then you really have got a bargin. Does it have 3 or 4 slots? The fiber version differs in that it has 4 slanting slots along with paper holders to support fiber paper, it's only been on the market a few years and is very rare secondhand.
When I do big RC prints or fiber I set the temperature to maintain a dev temp of 20 degrees C. When I do 10x8 RC prints I go for a dev temp of 30 degrees C to speed things up a bit.
Have fun.
