I had an Elgato EyeTV DTT stick that, due to its bulky size, I kept knocking out of the USB port on the side of my laptop. Eventually some of the solder on the inside came loose and it now no longer picks up signal.
This PCTV 74e tuner is an absolute bargain for a replacement. It is recognized by, and works immediately with, my EyeTV 3 software (Mac OS X), rendering an excellent picture. At this price, I picked up two! The other will go on my Mac mini that'll be used as an HTPC.
The adapter that converts the device to use a standard co-ax input from a rooftop aerial is reassuringly heavy, and connects firmly to the USB device. The tuner gives off a mild blue glow when plugged in, but it's dim enough not to disturb.
NB: don't be fooled by manufacturers who say that USB Freeview tuners work with those dinky little mobile aerials they supply - no-one who has any experience with USB tuners ever expects those to work. Don't buy this unless you're providing a good, strong signal.
Otherwise: don't miss out on this bargain price - you won't beat it on eBay or anywhere else!
