Gazza,
I'm really sorry to hear you are having problems getting brackets for your 1010i's, i was fortunate and managed to plan ahead as i was thinking of going to 7.1 from 5.1 and bought the brackets when i saw them 'just in case'. Of course i went with 7.1 after buying the brackets so don't get your hopes up that i will sell them lol.
I do have a suggestion though....from looking at the design of the 1010i bracket i can see no reason why you couldn't get some made for you buy a reputable mealworkers. I have several around my way (essex) and after a few enquiries they were happy to make up a set from my brackets design, now i realise you won't have a bracket yourself but a picture and dimensions would be enough to enable you to have a set made for you.
As for cost well they will cost you more than buying them at retail but certainly not over the top, i would estimate around £20-£30 maximum to get them made for you.
I can't see you have any real alternative as the 2010 bracket will not fit due to the new range having the binding posts in a different position and the fact that i, like you, can't find a single pair of brackets for sale anywhere on the net. You could try advertising of course but i doubt you would get much luck due to the nature of the product...i can't see the brackets being widely used.
You must be really frustrated and i can totally understand your pain so if there is anything else i can do to help just post on this thread and i will endeavour to help as much as i can, could provide pics and dimensions for example (hope this dosen't break house rules!)
