Reading this thread the bkool sounds very buggy.
Shame if that is the case. I love technology but when it doesn't work it drives me crazy.
I think generally people are happy with their BKOOL's but as with any VR trainer there will be small hiccups. I think a lot of the issues people have are really small annoyances like ANT+ drop outs but some others do have hardware issues which in general BKOOL support are quick to fix or replace under warranty.
It does look like the BKOOL software feature set and overall user experience has improved since I returned mine, the BKOOL website looks a lot slicker but is it more user friendly in terms of searching video routes which was what I hated about it before. The Pro BKOOL is appealing to me, especially now that it can be bought for the price I originally paid for the first gen one.
I have still yet to see a trainer that appeals to me in the same way as the BKOOL does or did in terms of value for money. I looked at the Tacx and was put off by the cost of the DVD's and the forums looked like they had reliability issues and also the gradient resistance was not as good as the BKOOL. I also looked at the Elite Realtour but after posting a question on their user forums and not getting a single reply for a few weeks along with the lack of web based reviews I decided against one, also you have the cost of the DVD's. When you look at the cost of a BKOOL subscription and what you get for your money compared to the cost of DVD's you cant really go wrong.
