I picked one of these cheapy Ammoon things up. I use it at every rehearsal and I've even gigged with it a few times. Nobody has once said "I say old chap, are there some latency issues with your tiny wireless dooflip?". Yes there is a slightly noticeable delay, but it makes no difference to what I play or how I play it. Unless you're incredibly precious about your sound, I'd recommend it heartily, especially if you're only playing at home.
