If you haven't seen these, you may wish to take a look:
3 units compared (including a denk standard and TV)
5 units compared (including a Denk and a TV)
Todd Gross's site at http://www.weatherman.com also has a nice section on binoviewers.
Since it may be useful for you to have some background of where this information comes from: I have no connection with either Denkmeier or Televue, except that of a satisfied customer of both companies. Nor do I manufacture or design any astroproducts. I do however, do a lot of stuff with cloudynights.com, and am very lucky in that I get a chance to see a lot of different equipment. Personally, I found the Denk Standards and the TV's to be very comparable overall with a slight edge to the denk in a couple areas. I found the Denk to be a little more flexable system with their magnifications (IE lower and higher power compensators in the same unit), however if you don't want to mess with the OCS, the televue compensator is a little easier to deal with, but it locks you into 2x, and although it seems like there should be full field illumination, I've heard reports of vingetting on fast dobs - have no idea what eyepieces they were using tho. If that thought bothers you, you would be best to seek out the yahoo binoviewer group, SAA and assorted other forums where you might encounter fast dob users and ask them directly. I also thought the denk went little deeper in LM (but not really much). I also had problems with the TV unit in cold weather - the interoccular adjustment froze solid. FWIW, I've seen this in my nagler 3-6 zoom too - just this year. Not sure if it's a simple adjustment, the lubrication they use, or if I'm just out in colder weather than I should be . If you live in a warmer environment, it more than likely won't be an issue, but if it were, well - IME TV, has great customer service. There aren't very many other *big* companys out there where *anybody* can call up and talk to the owner / designer of your products. That's just one of the reason I've had 4 TV scopes, most of their eyepeices and probably will pick up a few more. Incidentally, Denk has great service and support as well.
After a 3-4 month comparative test/review period, I wound up buying the Denk and sending the TV back. Well - let me amend that. I kept the Denk, till I picked up an FMC, and now I'm seriously considering buying a Denk II that I've been sent for review.
But if you are looking mainly at the TV or Denk Std, well - depending on your requirements, you could easily be happy with either as they are both good units. Only you can decide what units fit your styles/scopes better.
Keep pulling through the noise, there's signal out there, you just have to find it.
Just my .02 cents.
