why dont you write a review on the two machines and post it on your site? That way if others have the same question as you they can find a answer somewhere else if they search -) you need to be fair in your review as thats what you expect yourself. if people only have one place to go and ask those type of questions the conversation can be controlled you live in a great country that allows you to express your views.
A great way to do this is with a wordpress blog that other like your self can comment on. They are easy to set up. lets not forget google like reviews. so if someone is searching for a product a blog/page like that stands a good chance of being in the results. if you dont want to write it yourself this link below you can find people that for a very low price write it for you. this will work just as good as if you have the comment open on the blog people can write what they think about the product
https://www.freelancer.co.ukwhats really interesting about this kind of thing is that its prospects with the biggest objections that can become loyal customers if you can debate the objections. so if you dont answer these and win them over its can be a lost customer. I am sure that many on here have had the Portable TM talk with prospects and I bet it can go both ways depending on how its handled.
One big thing that I have always thought about this forum is it has a wall around it so google cant index this conversations. unlike other forums in this business that dont. now if this forum is run for the benefit of its owner then thats a massive mistake. and like this case people cant get a balanced view if they dont know this forum is around and that can be many new people coming into the business. that why other forums control things like they do because they know new people will latch onto the first expert they find and if that expert has a vested interest then that benefits them both.
