Personally I reckon it's a pretty good buy. There are a few things not correct about it but it is a good looking restoration and I've heard these guys work is fairly good. You would be hard pressed to buy an unrestored van and restore it for less than the price they are asking. Windowed or windowless is a personal thing and if you don't like the windows you can always have them filled in, I don't think having windows devalues them that much... maybe a few grand less than a windowless if you really don't like windows.

This one apparently is all matching numbers with original engine..... a restored Mandarin Red HJ 253 4sp HJ Sandman sold early last year for just over $25000 and it had windows and a later blue motor, also had a few things not correct on it.

I believe Sandmans are undervalued at the moment, particularly vans and I think their value is only going to increase in the future.
