go with the aqua C remora. I was thinking about the excalibur as well. spend the extra $$ and get teh nicer model. I got the urchin model on order. where may i ask did you see the excalibur? i havent seen them too far from the DC area
Good Choice, apparently the excalibur's do pretty good but from what i've heard and learned so far, spend the extra buck on equipment and you wont regret it.
