http://stores.ebay.co.uk/The-DTR-Store - can get em from £34.99 on there at the moment, I have in the past seen them for even less than £30! Don't get them from topuptv.com as they often try and get you to sign up to a months subscription to at least one of the viewing packs as well, all of which they do give you for "free" for the first month, but they carry a lousy £20 "connection fee".
Yes, the eBay account is actually TopUp TV (the other ebay store under the name TopUp TV has ceased to operate presumably because it was selling only brand new boxes, whereas we only supply recon stock nowadays through our direct channels).
For the record, we are still developing the software on the boxes, on the G1 for instance (Thomson 6300), we have had three new builds since v5.08 was released publicly last December and just last weekend we started working on a new build with yet more bug-fixes (all minor as there has been no major bugs since v3.59 iirc) and new features, so we are still developing the box software even though they may be some years old now and will almost certainly continue to develop them into next year to ensure they remain as fast, functional and reliable as possible. Id expect another public build update to replace the Dec09 v5.08 build to be released via OAD probably around August - September time. No news on mux recording yet, but give it time, we are likely to lose some DTT capacity in the next 12 months so unless we gain some more from somewhere (unlikely) mux recording is the only way the TV Favourites and Picturebox packages will be able to continue to operate. Mux recording would in theory allow upto 14 channels to be recorded at once (though in practice the boxes can't cope with the I/O load, so expect between 4 and 6 channels recording in reality).
And we are launching Sky Sports in August, just in time for the new football season for anyone interested lol.
If you need any advice regarding the boxes, feel free to PM me
