Unfortunately I have to agree with the negative comments with regards to MD, I paid a deposit, then sometime later was asked to pay for the machine in full as it was about to be manufactured, I paid for the machine in full and waited......
When the machine did not arrive on the agreed date I phoned MD and spoke to them asking for a delivery date they said that they could not commit them selves to a date , and it could be some months, at this point I asked for a full refund which they agree to.
After this conversation I tried phoning MD many many times and also recorded letters were returned un-opened , one of my last attempts at contacting MD I left my work telephone number and MD did leave a message on the answer phone that I would receive a refund as requested.
I dont know if the official sounding message on the answer phone at work or the idea that MD was not dealing with an individual, very quickly after that I did finally receive a full refund.
The fact the omega worked at all was quite a technical achievement it may have never delivered the fabled arm twister but it is a shame to loose someone of this technical ability from the RISC OS world.
I must admit that if MD came out with an Iyonix (which I now own) beater I would be very wary to purchase it because of the level of customer support that MD has shown.
