Some people can by the most expensive Ro/DI unit on the market and still have issues
And
Some who buy the cheapest have wonderful experiences.
Price and who makes it doesn't always mean that it is a cheap or insufficient product.
You pay more for an acura, but its still a honda. Honda transmission and motor. OH but it has pretty leather and A gps system.
SO some things may seem better,because they are more expensive, doesn't mean they are.
And board members on here have those "cheap" ro/di units and they work just as well.
you learn from experience, not reading posts by people that think one way or another. That think there ro/di unit is better then yours.
One thing I always point out to people on a daily basis.
IS people only post or respond or call tech support for whatever product, only when they have a problem. People post only when they dislike one thing or another. Perfect example, Apple Macbook pro's with the whine and heat issue. Hundreds of thousands have been shipped, but a few thousand say 10,000 have problems. So they all post on the web and make blogs on how they feel ripped off and how they hate apples. but what about the other 190,000 Computers that work... see my point
Best thing is for you To find someone who has one and ask them to look at it, ask them how its been running and take a taste test. ok well maybe not that.
and make a judgement on what you see, not read.
