In reply to blurty: You can get a genuine Humax replacement remote for a reasonable price eg item number 390448949447 on a well-known auction site.
To the OP: I'd echo the recommendations for the Humax HDR-FOX T2. It's only got two tuners, not three (I don't know any PVRs which have three tuners) but it's basically a rock-solid box. I've had mine more than two years and it's been 100% problem free. There are some reports that the 1TB version is a bit flaky, so I'd suggest steering clear of that one. You can get reconditioned ones from Humax' direct sales web site.
Don't get the Humax wifi adaptor, there are cheaper ones that will work available on Amazon and elsewhere. I used the Edimax EW-7711UTn before I ran a proper LAN cable to my AV stack.
Oh, and there is a slightly convoluted way to "record" three programmes on the HDR-FOX T2 if you really need to (although you do have to be present for the end of one of them).
There's a good user community for the HDR-FOX T2 online with a number of forums where people share ideas and advice.
