Hi Robin, welcome to the forum!
Great choice a Dormy! Only slight downside is how high up the bed is and thus how close to the roof you are! Otherwise really light and airy with the roof lights and vents and stacks of head room when roof up.
You don't say how much you are looking to spend but there is a real beauty on ebay now ( not mine or anything to do with me!)
