I sail a dagger
Your post has been up a while so I'm not sure if it matters any more but I sail one of these boats and I love it. I got a used one a year ago for very very cheap and I now realise what a steal it was.
Not many people sail them, so if you are looking to race I'd stay away but if you are just looking for a fun boat to sail alone or with one other person onboard I'd get it.
Should weigh ~180, mine was used and abused and weighs more like 280 but still sails well. I'd love to have seen it when it was light and new!
I have a copy of the original manual so if you need rigging help I can send a copy along.
