Retiring ray-vac...... options?

Retiring the ray -vac pool cleaner, worked great when it was new but since has been thru its share of abuse(teens...need i say more), i'm considering either the legend(kreepy krauler) or the polaris 360, and would appreciate feedback from those who have one or the other(thegood, the bad and the ugly). i would also like to know if i can get a adapter to go from my pool wall to the new cleaner or is more work involved in changing fittings? currently my pressure line just slips into the hole in the wall and turns about 1/4 turn and its in..... thanks again.
