Some info considering the land prices.
Considering the current block price of 0,05g, it comes to over 1600g/chunk. I can live with it. But since you can't expand existing land claims in residence, making large enough claim at once becomes a necessity, and expensive one at that.
Also any mistakes you make during claiming come at a steep price because unclaiming(removing) residences offers no cashback. I had to remove my original claim to replace it with a larger one at the same spot. So be warned everyone, plan your claims carefully.
Lowering the block prices would again cause another problem we didn't have with towny. Because there are no claim limits like 8 chunks/player in residence, a rich player could obtain insane amounts of land.
