Check out Worthington distribution for the filters also....same 
filters, but much better pricing.

See:

I've used both the 5 amp and the 15 amp filters, and for most 
applications they work well. However, there are some cases that 
the filter can't solve completely. That's when a repeater 
probably would be a good investment. I haven't tried one yet.

However, I'd want to try to clean up as much crud on the line 
as possible with filters before going to the repeater. The Elk 
ESM-1 Signal Meter is worth it weight in gold when it comes 
time to troubleshoot these types of problems. See about a third 
of the way down the page here:

I just use an X-10 Burglar Alarm Interface module wired to 
transmit an X10 code continuously where the CM11A is normally 
plugged in, and test all the X10 module locations with the 
ESM-1. It took me just a few minutes to find a LOT of 
interfering items, including 3 computers, 2 UPS's, 3 TV sets 
and even a paper shredder! Now missed X10 transmissions are 
a rarity.

(I don't work for Worthington Distribution...they just seem to 
usually have the best prices when I need to buy something.)
