In 1998 or 99 (can't remember) I purchased a full set of energy e:XL s.  The center and the two front towers are still going strong. The rear speakers have, however, died.  I've been using two small infinity speakers in their place.  I've just upgraded to a 7.1 receiver and I'm about to move to a bigger room with all brick and concrete (and a rug).   So I'd really like some advice on two things:

1) What would be the best set for the rear and side speakers? I'm considering just getting a take 5.1 classic set and keeping the 5th speaker and sub as a back up of sorts.   But I'm not sure if they'd do well in a 22'x22' room or not.

2) Who, online, typically has the best prices and reliable reputation for dealing in energy speakers?  I remember joining some online discount club and getting these energy speakers at an excellent price.. However, finding energy dealers online has become a bit more of a challenge.

Thanks,

Trey
