The BT3000K was the last model of that type to be sold in the UK. I understand that the BT3100 has just been made available in Australia (240V), but my enquiries about the possibility of a 240V UK release met with this response from Ryobi UK:
"Good Afternoon, I am sorry that I have to reply to you with no so good news on the above machine. This is not a model that Ryobi UK do or will do. We are a separate entity to Ryobi America/ Europe/ Zew Zealand, this therefore means that we will not have the same range of products and unfortunately do not know what other country's will be selling."
The 3100 is marketed in the USA through Home Depot, but is 110V. I know of at least one user who has brought one over with him and used it with a transformer, but I don't know what - if any - effect that had on its cutting power.
I bought my BT3000 second-hand some years ago and have been very pleased with it since I stripped it down and had a good old clean and adjust. My mobile cabinet was one solution to a greater rip capacity and a safer way to handle sheet goods. Not perfect, but better than nowt!
Ray.
