i have all 4 and they were worth every release date penny out of my pocket...im not sure what i paid for each...somewhere around $60 im sure
as for csi: miami, i also have s1 of this....i watched the first 2 episodes and while they're alright, i just haven't been able to get into it as much as the original....not that im giving up on it just yet....i just have too much higher priority dvds to watch before-hand
