Hi and welcome.
Based on your post I'd say you have some serious research ahead of you. Not sure the "Chinese Cheapo" comment is even accurate anymore either as almost all VU+ production is now China based and Chinese Dreambox clones have outshone the orginals for years now. My DUO2 was made in China and yes it is genuine.
The simple answer to your question about boxes in general is you get what you pay for.
I have the Duo2. I'll be honest, as I was nurtured on Dreamboxes, it took me a while to warm to VU+ but I have never looked back since I bit the bullet and bought one. The Solo2 would have actually done me nicely but having had a DM800SE for so long I had fallen in love with the, to some silly, LCD display on the front. The one on the DUO2 is a beauty and configurable to ones hearts content to even display a rolling Powerpoint type presentation while you watch TV. There's a great thread on this very forum with a fine example of this. It also has quad tuner capability and these are plugable as oposed to being fixed on the Solo2.
OK the Duo2 is megabucks and TBH the LCD thing is a bit of a gimmic. So we are actually back to the Solo2 or are we? There are other contenders out there that should not be ignored. The Gigablue Quad for example. Check it out on the forum sponsors website. You'll be quite surprised at how close its spec is to the Duo2's and for around half the price.
Decisions, decisions..........:snicker:
Styboxes and similar are pretty basic but not completely without merit. They are ideal for those who can content themselves with clicking and watching or as a second bedroom box. They are a big no, no for the real sat enthusiast and the tinkering that accompanies such a personality. Also totally out of the question for multisat unless you are willing to spend hours chopping channel lists down to size to allow adding selective channels from multiple satellites. Not sure if they ever got the EPG, PVR or advertised Mediaplayer to work as described either. Certainly never did during the time I had the misfortune of owning an S10.
If you want a box that is progressive, customisable and continually evolving then it has to be an Enigma based box. Ultimately the choice has to be yours and yours alone but one of the most important factors in deciding is to ensure the one you choose has good image support and is well spoken of in forums such as these. The Solo2 would fit this bill perfectly.
If you can root and flash a phone (Hd2 for example) then flashing an E2 box and setting it up will be a doddle.
Finally, if you have cancelled your sub you should know that to get adopted into any CS ring you will need a valid sub of your own to share with others else you will not even pass go. Doesn't have to be an expensive sub but is should be one that is desirable to others.
Good luck in your quest.
