I think they're about £900+VAT from Merc. Vos list them at £3??+ used but rarely have any.

The condition of the gears and seals would be my first place to start. If they're left standing the top gear is above the oil level and can corrode, which then causes slack/failure when they are returned to service. I understand they're not cheap to get parts for.

I'd pay £500 for a good one. Everyone who I see with them wants more, but I think any more than that and you may as well buy new. Also, make sure it has the mounting bracket included. I wish I could even find one. It's the last bit I need to get mine doing what I bought it for!
