I have experience with the ULX and SLX systems. We currently have four ULX Pro Receivers, four Beta87C transmitters, and two
bodypack transmitters with WL93 capsules. I absolutely love the ULX systems - they have rock-solid reliability, they have decent battery life, and they are rugged. I'm not so fond of the SLX, as I have yet to get decent reception from over 100 feet with them (with 1/4 wave antennas). The ULX works at 150 feet plus with a
clear line of sight.
Some things to consider:
1) You must have a receiver for every mic you want to operate at once. That means if you need both a
bodypack and a handheld at once, you need two receivers.
2) The WL183/4/5 capsules are large and bulky, and are very difficult to hide. The WL93 sounds great, and is cheaper to boot.
3) I saw that you specified the J1 frequency band. Be absolutely sure that this is the best band for you. Go here and run a frequency check on your area:

4) See if you need the professional receiver. The differences are outlined below, courtesy of
Shure's knowledgebase.

5) If at all possible, try them before you buy them.[/code]
