All great setups

The line6 one isnt all that bad and normally I dont think of line6 as a higher end company. They are starting to put out some good products these days.

As far as wireless goes, you get what you pay for. I would be skeptal to get any wireless under 600 bucks. All the damn money i spend on guitars, amps and effects, last thing I want is to give them a bad signal from a crappy wireless. Best advise I can give is to spend a good amount of money. Wireless is the one area where you do not want to go cheap.
