This is an older unit, but I bought a Fostex XR-7 4 track like 6 years ago and I still love it, although I use a DAW now.
Regarding customer support, I have a good story to tell. Maybe 6 months after I bought it, my mixing/recording level meter went out. The warranty was up so I took it to our local pro audio repair shop. They repairman said those things are vacuum packed and sensitive to drops, but I told him I really had only used it maybe less than 25 hours at that time and it always sat on the same little table in my music room. I even made a cover for it to keep the dust out.
Well, he opened it up and looked over the outside and noted that everything was in mint condition and that it obviously didn't take a fall, so he called up Fostex and told them about it. They sent him the new meter reading gauge for free and paid for all but $20 of the repair cost for his labor. I was appreciative not only because he didn't have to do that (I didn't ask him), but they didn't need to respond like that since the warranty was up. They saved me about $150-$200.
This was years ago but I never forgot their kind response.
