After a lot of reading up, i came to the conclusion that the 500HD might be good but was over priced.
The lowest i could find the 500HD was £310 in del/VAT
I have just got my new Vu+ DUO a TM Gold 0.1 QUAD LNB and 3m Lan cable for £375 inc Del/VAT.
Apart from the obvious twin tuner, the DUO also has many more connections a larger case (to aid cooling) and a great new image...VIX 1.1 !!!
Build quality is also top notch, and the front display is clear and easy to read. Even the remote is better.
The DUO is no slouch, and the image quality stunning.
Dream have milked people for as long as they can, the 500HD should have been around £200.
The game has changed/moved on, and for the sake of £40 (or less if i sell the QUAD LNB etc) you are getting a much more rounded machine.
(that is also well supported on here)
