vega dead a decade ago :-)
for entry level - sennheiser g-2 about 450 per system
or Audio technica that has dual diversity reciever -about 1300us ( 2tx +rx)
for much better performers and much grater price range the micron ,lectrosonics , audio ltd and ZAXCOM( something that most close to what 30$ cable can give you :-))
1800-4500 per channel , depends on the model .
the sennheiser, even the sk series really dont come close for these 3 performers in the field
the sk is waist of money if you ask me .
you can find good used lectrosonics or audio ltd 2000 for much less , even they are 4-10 years old they bit shit from the new toys in 500us $ range for quality and durability
