I has a Boss loop pedal that, which sucked to do things KT-style.
The AKAI is really handy. It takes some getting used to to get the timing right, esp. your basic loop has to be correctly ticked on and off. Once you've got that, you just build on it and timing with your foot clicking isn't really an issue anymore, because you just play on your basic loop.
Also it's got a delay and echo delay function, so that's a bonus. You can't use them together tough.
Fair warning: I didn't find it in stock in any of the music shops I went to, but maybe that's just here in Belgium. They had to order it and I had to wait for two weeks or so.
But I'd say it's been well worth the investment up to now
