my experience is similiar to gresh's...i've had the loop station for a few weeks now, but haven't had a lot of time to spend with it. i did gig with it (i do a solo noise/ambient project) this past saturday, and it was definitely the key to a sucessful and well received performance. i used it more as a looping sampler, loading up 4-5 samples earlier in the day and then just playing them that evening. it has a cool reverse function that you can click in and out for some great sound warping. my friend has had it for a year or two, and i played around with it quite a bit when he first got it, and the overdub function comes in quite handy. as a guitarist, its not very foot friendly without the additional boss footswitches, you can pretty much just do the record, play, stop, and overdub with you feet as is, but you have to use your hands to switch between phrases and switch on the reverse function. but as i said, these functions are footswitchable with 2 additional footswitches. the main advantage of the loop station over the line 6 delay modeler is the length of samples that you can do. the line 6 is really a delay pedal with one loop setting, whereas the boss is a looping sampler. so the 1 min per phrase of the boss is a huge advantage if you're going to use a lot of looping...look out robert fripp!!!!
