The RDRHX910 combines a large array of features and options with a huge 250 gig hard drive. Unfortunately, an equally huge $1499 price tag and poor integration of many peripheral features detract from what could have been a standout recorder.

A wide range of supported formats, combined with stylish industrial design, makes the KiSS DP-558 a great hard disk recorder for the power user who doesn't mind recording in MPEG-2 and archiving footage regularly.

This recorder is a beast. High-budget users will find the RH7926W to be an outstanding unit, delivering top-end performance with a sleek and user-friendly design.

The Sony SVR-HD900 is an easy to use and feature filled hard disk recorder with 250GB of space for both standard definition and high definition TV.

LG's LST-5403P is a top of the range hard disk recorder with plenty of storage space and an interface grandma could use. A great, albeit pricey, contender.

An absolutely fantastic device, with only a few slight problems and omissions. If the firmware updates go as planned, it has the power to become a truly revolutionary product.
