Unfortunately the Masterlink is listed at B&H as discontinued. Sweetwater.com lists it as out of stock but expected to be in stock shortly. Not sure how much confidence I would have in that.
Here are some other pro-oriented recorders offered at B&H, including a couple of Tascams:

If the latter, I would suggest using a high quality compact flash recorder, then transferring into a computer via firewire or usb (depending on which interface the recorder provides), or via cf card reader.
If you want a really top-notch cf recorder, and are willing to spend $1875, I would suggest the Sound Devices 702:
