The Company issues the Telex 850. Doesn't give you much protection IMO. Some use the UFlyMike setup.

I have been using the A20 since it came out. SWAPA has a rebate program with Bose for it. If you are considering it, I would wait until you are here.

There are two rebates:
A20 with Bluetooth - $150.00
A20 without Bluetooth - $125.00

The info is on SWAPA's website. Probably they will tell you about when you show up.

Welcome aboard.
