Rolling stand for MX-5050

[thenapking]

I need a stand for my mx-5050 biii. It's the large 8 channel version which lies down. They don't turn up on eBay very often (although there is one there at the moment - HANDS OFF!). If I don't win that, what would be a good alternative. Can you suggest anywhere in the UK where you can get these or similar? or is there a stand for a more common piece of equipment that can be cannibalised?
