The only advice I can offer is to keep watching Ebay. Stands will more likely be advertised as RL60 or RL60.2. There are two different types, earlier ones have parallel vertical bars terminating in a horizontal bar - later models have vetical round tube terminating, again, in a horizontal bar.
The tube models are more rare, and in my mind more attracitve - I have the parallel vertical bar models.
Note that the RL140 stands are significantly larger and are not suitable for the RL45 or RL 60 models.
Good luck!
