Query: Familiar but I'm on my 4th one

I'm on my 4th one, mostly because it's so familiar to me and I have a hard time finding a similarly-priced unit that will do the same thing. BUT MAINLY BECAUSE I HAVE TO KEEP TAKING IT BACK UNDER WARRANTY!!!!!! Do NOT buy this unit without the extended warranty, it WILL give out on you.
